FIY. An LCD-screen with I2C backpack only uses 4 wires. Maybe u already know this?

Main Thread updated with HOWTO info. http://forums.eagle.ru/showpost.php?p=2689981&postcount=1

Yes, its very close to working. Took me <>4 days = 16 hrs of experimentation. FYI. I bought a chinese CNC 3040Z-DQ with limit switches of ebay. Also, replaced the Mach3 parallelport for a Chillipeppr USB Motion controller. Its got Nema23 stepper motors. VERY IMPORTANT accuracy settings; Measurements $gun=0 (G21 millimiters) Limit switches = NC (Normally Closed) Motor 1,2, 3 Micro Steps=Eigth Motor 1,2 Travel Per Revolution=4,1 mm/rev Motor 3 Travel Per Revolution=2 Step Angle=1,8 Below. Try-out PCB etched into wood for Arduino Nano. Non copper regions=0,2mm v-shaped bit. Drill holes=0,8mm ball nose bit. (which bits do u use??) Earlier failed test runs :P. Trying to reproduce a DirtyPCBs-version on my own machine. Things to note; 1. Travels per revolution is VERY IMPORTANT!! Its influence for the scaling. 2. Stepper motors must be tightend very well, otherwise the ballscrews wil lwobble causing erratic patterns. 3. For this particular CNC, wire the limit switches all to GND, then per limit switch connect it to the relevent TinyG limit-switch. 4. To protect motors from damage set limit switches should be Velocity Max=400 mm/min. Yes its slow but thats a safe margin. On Z-axis set limit Min=homingand Max=Limit Only. 5. Emergency STOP button: easy peasy. Just plug it into the TinyG reset-pins. 6. I suppose ont can use a USB-based GRBL controller with Chillipeppr too. I bought a TinyG coz i wanted the best right from the get go. TODO: * Connect the Spindle to TinyG. anyways, its an ongoing learning effort. Tomorrow maybe i will etch my very first real PCB. I am kinda proud of myself. Got this far with only youtube, internet forums. The wife doesnt get it..

Finally my CNC 3040Z-DQ has arrived from China-CNCrouter. Overall, i am VERY HAPPY. But, let me report back in a few days again ;). The machine is sturdy, all solid ball screws with limit switches built in. The controlbox has a parallelport for Mach3. Ofcoz I changed it to a TinyG USB controller :music_whistling:. Setting up TinyG took me about >=3 days to figure out all the wires as my electronics knowhow is severly limited. I havent milled anything yet. Using a markerpen plotted a PCB onto wood. Before commiting to the real deal of PCB etching. The machine was 95% pre-assembled. One only needs to hook up the printer cable, mount the Nema23 stepper motors, tighten some small screws and you're ready to go. Thats the theory. I am still learning about homing, limit switches etc. The kit is quite complete coming with 4x drill bits, z-minimum probe, tools, reserve limit switches. After scratching my head,the limit switches are now also connected to TinyG. I have them setup for homing. Dont know how homing works yet, but will figure that out l8er. My toolchain; * FREE http://chilipeppr.com/tinyg . This is equivelant to Mach3. * FlatCAM --> Converts GERBER-files to gcode. * KiCAD for PCB designs. So far i am happy :) TODO: * Write a small blog on howto get TinyG going + my experiences.

The Alternate Flaps doesnt work on my Warthog throttle. Expexted behaviour: Switch up = MiG-21bis flapsbutton 1 Switch MR =MiG-21bis flapsbutton 2 Switch DN =MiG-21bis flapsbutton 3 Thats how its working in the A-10C However, in my Alternate flaps, only UP & DN works. I suppose the Flaps is an 3 position SPDT-type ON-OFF-ON switch. any ideas..?

I've orderd a Chinese CNC 3040 from ebay. Its already 90% assembled. Hope its a good thing ;).

Good tips :). I just ordered sum for use with LED strips. You mean, with using a RS-485 slave..? I had one on my PCB but seems like DCS-BIOS doesnt like it :P. My sketch wont compile. It says it needs a Arduino Mega :joystick:

This thread is to concentrate questions about elekctronics in one place. Similiar to the DCS-BIOS discussion. DCS-BIOS + Arduino's is cheap (<=€5!!), easy way to interact with realworld buttons & controls in DCS World aircraft. =============================== To kickoff.. Backlit my MiG-21bis custommade arduino Nano shield. HOW?? I have 2x I/O pins available. Apparentley each LED should be connected to a resistor. The picture below is only the PCB. Q's; 1. Can I use a 3x LEDs which gives enough light to lightup my PCB? 2. Should i integrate LEDs into the PCB design? 3. Did u use a LED per switch/button/whatever? If not why not? How? 4. Should i rather change to a Arduino Mega? If so, why? 5. How did u backlight each control in your cockpit? Did u use a dedicated Arduino to power the backlighting..? 6. other tips, or insights to share? This is my (current) design. TODO: panelmaking by CBC router.

Why are there so few RSBN channels in the L-39's RSBN nav? look here http://www.digitalcombatsimulator.com/en/files/1514733/ Only 4 airports with RSBN channels?? In the MiG-21bis there are far more, or is this the real-life situation around th kavkaz region?

Selling, no. Coz this is a test-version. However, i can send u can be a beta tester.. however, i will ask €'s for the components used & Arduino. Cost? Just a little more than a McDonalds Big Mac + fries + cola + McFlurry. Its plug'nplay. Install & get DCS-bios running (i.e. add a line of code to export.lua) and its working. Takes about 2 minutes. Thanx :) Stuff i used; * Software. KiCAD -- Open Source for the PCB designwork * Ordered from Chinese company http://dirtyPCBs.com for the PCB manufacture. Their cheap and VERY good. * Wanna know more, PM me. U R welcome to write in Deutche sprache, i'm trying to learn ;). TODO; * Implement backlighting for the panels. * Move the Max487 IC about 8cm to the right. * Move the RJ45-connector next to the I2C-headers. * Add 3x expansion headers, so one can use the PO-750 Circuitbreakers Obstacles; 1. I dont know the real cockpit dimensions & spacing between buttons & switches. LN isnt exactly forthcoming in this regard. 2. Manufacturing PCBs to real life scale could be expensive. Likely, one would need then 2x PCBs for the main powerpanel. My solution: space switches close to eachother. 3. Funding €'s to R&D and build new prototypes. Wannabe betatester? PM me. I can afford 2x beta testers.

here's my latest MiG-21bis Main powerpanel, featuring RS-485 integration. its a custommade Arduino shield :D :D I made design error.. the USB is pointed to right, interfering with the RJ-45 (to be soldered). my dcs-bios shield has got; * I2C-ports, for expansions * 2x dualpurpose (analog) expansion ports * Custommade silkscreen logo. It was made by http://DirtyPCBs.com

here's the latest version. A custommade Arduino shield :D . Look, all wires are gone. Featuring DCS-bios integration with Max487 linkups

U need to enable it, its a toggle switch just behind the flare dispenser, on the backside of the throttle.

DAMN. I just ordered a Chinese CNC 3040 a day or two ago. U shouldda posted in this http://forums.eagle.ru/showpost.php?p=2700651&postcount=31 place. Whats your aking price? Whats the specs?

I didnt read this thread for a long time. Whats ED doing with the Vive? Any official news from Wags?

Hi Clay, gadroc, John & lurkers :) I took the plunge. I bought a Chinese "CNC 3040Z-DQ 3axis Router Engraver with limit switch with 1204 ball screw". I read the forums as advised. I am scared sh*tless.. Its expensive!! Total price=€889 to be shipped from Deutchland. The seller has his stock now on sea to the EU. [edit]hopfully to receive it by 25-3-2016[/edit] Software & controlling is still a problem. I consider to buy a TinyG USB controller for use with Chillipeppr & bCNC. Its supposed to be an alternative to the UC100 controller. Questions; 1. Has any1 of u stuck a CNC USB Controller into the Chinese CNC machine? If so, which? 2. Does a TinyG controller work on other open source software, such as bCNC? 3. Can i use a UC100 controller on bCNC? 4. Which (free/open source) alternatives are there to Mach3? 5. FLATCam seems to be an Open Source alternative to CAMbam. I tried it on my laser cutter. Any1 als also have experience on FlatCAM? 6. Which engraving bits are best for PCBs? Carbide flute, tungsten..? 7. WHich bits are 'best' suited to milling woonden/perspex panels. Considering i might break a few.. 8. other words of wisdom? I ask here, coz maybe other guys on the ED forums also wanna build a pit, and buy a (Chinese) CNC. This way, we can share experiences, and concentrate it in one place. Eventually.. later on i could do a small writeup / FAQ of my experiences and publish it here summarized as a single closingpost in this thread.

Tx 4 the tips. I posted on CNCforum but didnt get any response there yet. Clay, your experiences will be invalueble to others whish to dive into Chinese CNCs. Maybe u could summerize what u learnt here, plus the DOs and DONTs of (Chinese) CNCs. Unlike CNCZone forums we both are into DCS and u already know about chinese CNCs. I read threads as suggested and noted on youtube that u had problems with the ballscrews. Since your positive about the chinese i am now seriously contemplating an order CNC 3040Z ballscrew-version. Whats putting me off is the parallel port. Yes, use an old computer.. but here in Holland the houses are literally pigeonholes. My hobbyroom is the size of the average American house' bathroom. So an extra computer/laptop.. its taking up valueble space. Which bits are u using, forexample to make holes, and/or clear copper areas example, for the UHF plate? BTW. UC100 is a parallel-USB interface adapter. Я могу читать и понимать очень мало слов. У меня была русская подружка ;) grtz, Michiel

TX John, and yes i have a loada questions now. Like which flutes to use etc etc. The past months i've discovred that specialist skills & experitse is scarce. If i wanna lknow about cooking the perfect lemon chicken, then every1 in my street knows/can do it. Ask about sumthing like CNC machining and u get blank :noexpression: stares . I'll head over to CNCzone, and report back on this thread l8er on. regards, Michiel

appareneltey also important; * Ball screw, limit switches, <=1mm accuracy, if 1mm = 1mm stepper on the CNC. More Q's 1. How much actual workarea does a 300mm x 300mm give? 2. Does any1 have experience with bCNC vs Mach3? 3. Would a UC100 Parallel-USB adapter work with bCNC? 4. Could i use a €15 Parallel-USB adapter with bCNC, or in Mach3 on a chinese CNC with bCNC? Condsider that i wanna make, and my budget is <=€1,000 all inclusive. Yesterday i watched a youtube vid on assembling the X-crve. OMG its gonna be tough.. And received notice from dirtyPCBs: my MiG-21bis pcb has been sent. Hopefully, whith my own CNC i wont have to wait 4 weeks.

I thought of buyng a kit such as X-carve or Shapeoko which are Open Source. Hoever its quite a complication to build those. In 1 of the threads John advised against building yourown.. unless you are experienced. My preference goes to a kit which is sorta assmbled. I watched sum youtube vids about chinese 3020's and they come pretty much assemebled, sum ppl swear that the Chinese stuff are good, others prefer more prof CNCs. Considering my budget.. Its either a X-Carve, or a Chinese 3020-machine. John, whats your opinion on a X-carve & Shapeoko 3?

$3,000 is waaaaaay beyond my pricerange. Ofcourse with a highclass router one can do a lot more.. but i wanna go for best of both worlds. I'm not gonna make computerchips. Its for my MiG-21bis DCS cockpit build I did sun digging. The Open Source alternatives; * X-Carve, cost <>$950 with 1200w spindle and 750mx750mm workarea. * Shapeoko 3 -- apparenely is an improved X-carve. * Cyclone PCB Factory, another small Open Source thing-a-majing. Cost estimated for 1x PCB, and about 4 iterations to perfection; 1. Home made, with cehmicals = €??? 2. 4x€15 with DirtyPCBs = €60 3. DirtyPCBs cost for 12 panels x 3 iterations = €540 (and waiting time=2 years) 4. Chinese thing. and considering the comments of Warhog. 5. biy X-Carve/Shapeoko, or tryout building Cyclone myself. I have 2 righthands.. As warhog says, a bigger machine gives more possibilities, and i can use it to cut bigger things such as panels. Which CNC would you buy primaraly for PCB milling, secondary for panel making? (and hope to be able to sell the CNC later when the cockpit is finished) * X-carve, Shapeoko, Chinese 3020, Cyclone PCB, chemicals or... forget it. meanwhile I'm gonna lookin into the chemical method.

LOL u know Den Haag?? Have we met in Real live?? :P I've been to * Revspace, its been broken since forever, and wasnt used much. * FabLab Den Haag, they dont have one. * Makerspace Leiden, they have a CNC -- very seldom used, and no experience on PCB milling. * Makerspace Haagse Hoge School.. same thing. No CNC router.

In my city, are 4x FABlabs. NONE of them have CNC, and i visted the labs. Weird..NOBODY knows about PCB Milling. Sum1 at such fablab didnt even know what a PCB is :huh:.
