what thickness copper should be used when one gets the boards made? 1oz? 2oz? 3oz?
Iāve always used 1oz. Iām pretty sure the stock PowerControl boards are 1oz. as well.

Thank you for the great work.
I just soldered together a thruhole version, but before I install it, maybe a stupid question:
- Do you need to change anything in the firmware if you replace the original board by this one?
Thanks for the feedback

No, GroundControl should report it as PCB v1.3. Donāt worry about the 1.4 on the board, itās ok.
Kind regards, Gero
Edit:
Not sure if you are interested in the firmware code 
, but just in case:
The motor driver board is detected in the System.cpp and the pins arranged accordingly.
Super , thanks for the explanation Gero 
Very interesting!

Iām trying to get a batch of these through hole boards made (SMD chips are no longer available). My PCB manufacturer says their are two āair wiresā in this design. See photos below. Should I be concerned about this?
Looking at the empty board I have and the pinout of the Arduino Mega, my guess is that they just donāt know that this goes on a Mega and that pin 22 has 5V. 22 and 23 have a connection on my pcb and the 5V connection to the additional headers is already there (If the second wire is on that thick red line). Am no expert, but both look not needed from my opinion.
Edit: For testing the DUE, I needed to cut the 5V (red) and have an air-wire from the other side, so 5V should be there if this goes on a Mega.

Thanks for the reply! unfortunately Iām not an electronics expert so didnāt really follow what you wrote. I just need to know if the community garden Eagle file is correct or if it needs these āair wireā errors fixed.
I was, over 35 years back, not any more. I gave you my opinion that the guys in China might not know that this goes on an Arduiono Mega and think that they have discovered a missing 5V. I could be wrong.
Edit: Itās all on the 5V line as far as I can tell, so it should not harm and can be cut off if it gets in the way

I believe that those error messages are safe to ignore, but I donāt have any experience with that board personally.
Could we compare it to the SMD version which you know works and see if the same āair wiresā exist on that one?
Same company made the smd boards for me they did not mention any errors with the SMD version. I canāt locate the smd chips anyways. The Through Hole ones are pretty much gone too. I ordered the last bit from mouser & Rochester. Digikey doesnāt have any. If anyone knows of other sources let me know. I dontā want to go back to the original or Due board because the 2 L298P chips might get too hot with a stronger/ better z axis. Old z axis motor has .55A and my new ones are 0.85a. If there was at least 3 L298P chips , one for each motor that would allow for a stronger z axis motor without worrying about the chip overheating and dying.

It is safe to ignore, just a NET warning, the board has a 5V āopenā net.
The warning goes away as soon as you rename the NET to something else
Iāve just changed it to VCC5 to make your PCB house happy

For anyone that wants to make this board in the future the 3 holes that connect the 12V dc power plug are too small. lower right corner. One will need to make them oval shaped to have the connector fit.
I doubt anyone will ever make this board since the TLE5206 chips are very hard to find, but it should be mentioned the files are not good as they currently are.
You are right, i sent you the fixed files per your request (PM) but never posted them here again.
So here they are just in case (oval shaped fixed)

Greetings all!
Question. Iāve followed Maslow since the beginning. I get distracted for a year or so and come back. Just reading up on the TLE5206. So, is the SMD version on this board not good? I just started working with a hot air station etc. So I am looking for a project to work on SMD.
I already have a couple motors I think are in speck.
Is anyone here selling the PCB? I donāt mind ordering from PCBway etc.
Thanks.

I thought the 5206 chip was on its way to obsolete with announcement of production stop earlier this year with final orders had to be placed by some time early this year so the next one is the 9201 or something else. Did you look at the thread on the esp32? there are new boards being made and tested if you are in to that.
Iāll take a look at the ESP32. I can find a bunch of the 5206 available. Maybe not good for production, But Iād buy 10 to have back ups.
i have 200 PCB for the TLE5206 Through hole with round instead of oblong holes for the DC jack. You can run a wire to the dc jack or drill it out. send me PM with address. manufacturer of our boards just made new boards up and gave me the old ones with this minor issue. Where are you getting TLE5206 chips? I can only find them in China.
The SMD chips are fine, I used to use those, but canāt find a supplier anymore.
Greetings!
Havenāt had much luck sourcing a blank 5206 PCB. But I will just use a Perf board.
Question: Iām looking at the circuit. I want to run at 24v. Should I need to change any of the resistors?
There are 2 LEDs on the board. Iām guessing they get their power from the Arduino? 5v?
I donāt see any Voltage regulators, so the Input voltage 12v or 24v is not feeding any of the 5v components?
The board calls for 270ohm resistors for the LEDs. Anyone know if I use 220ohm if that will be okay. That is what I have on hand.
The motors I purchased are rated at 24v.
Thanks
