Hey fellow Proforgers, here I want to list the bugs in the official firmware. Please add yours, if you find some.
First of all, I find it a bit irritating that you only get the .bin file and not the full firmware. They surely have it and it would make life with this printer so much easier!
These were the following mistakes I found:
- X, Y and Z Axis are inverted
- Temperature is very sure false (180°C smells very burned
- when loading and unloading, the Bed goes up like 4cm before the filament comes out!!! (Should be the inverted Z-Axis)
- when started the error „failed to enable Bed Leveling“ pops up on the screen
the rest seems to be working fine…
Answer from Makertech:
Thank you for your contribution.
Motor directions should be correct, they are working fine on our set-up, please double-check your wiring.
Temperature was calibrated with an external thermocouple, it should be correct, some burning smell is normal on first heat up.
PID should be correct too, but has been re-tuned. PID was tuned with fans at 100%.
Bed Levelling error on start up is normal, as no bed levelling has been performed yet.
Marlin source has been added, feel free to make adjustments if your axes' are inverted.
sounds great! :-)
Hi Frederik,
Just wondering if you have fixed the X, Y and Z Axis being inverted? I have the same problem and was wondering if it was a wiring issue or firmware?
Cheers,
Luke
Hi Luke, they said that the Firmware was correct and my wiring wasn´t, although I double checked. Nevertheless I compiled a new firmware which works fine and has fixed the bugs!
you can download it here:
If you know a bit about marlin, you can download the whole fixed firmware to compile yourself here:
Cheers back to you!

@Frederik Weis Hi Frederik,
Thank you for sending that over! That has fixed my issue with my inverted axis! Now I just need to figure out why my probe won't stop the bed when it should!
@Luke Westwood you can check with the GCode M119 which endstops are triggered, I used that to test my probe
Hello i could download the original firmware and recompile it to correct the inverted axes, so far all working fine! I am now printing a 3D benchy, will post update once finished
