What is the error that is displayed? Ensure the separate heated bed power supply is properly connected (you should see a light on the MOSFET board you installed) then verify the thermistor (really thin wire) from bed is properly connected to the main board. The PTFE tubing goes from end of extruder motor to top of hot end.

The Z end switch is your probe. Sorry, I didn't see that part of your message when I replied earlier. Z triggered means your probe activated. Recheck wiring according to manual. Is the red light on top of the probe active when you receive the error?

My probe, I think, is pretty well situated it's just strange that it only happens if I perform the G29 prior to a print but not any other time. If I don't perform G29 my print is fine (as far as layer performance) the only issue I have is that I can't print anything even resembling a circle. Edit: to clarify, the nozzle digs in when the print starts, after successfully completing the G29 command.

I do not. For some reason when I try that my nozzle digs into the bed. Maybe I'm not using enough points? I don't know anymore.

It's your Y arm. Front of the printer, make sure it's not off in the left or right direction, but also the up and down direction. That is, the part connected to the Z screw needs to be exact same height as the front of the arm. Also, the part attached to the screw needs to be in a straight line all the way to the front of the arm, in relation to the bed.

Yeah, I'm getting tired of having to fine tune before every print. My layers are looking decent, but the thing will not print a circle, always ovals.

Here is a link to the correct G29 behavior. https://youtu.be/3VLkyEEV1Kg

I ended up buying new cables on Amazon. They were also reversed, but actually functioning unlike the ones I received with this kit.

Video was too big for this site. Here's a link to my G28 command behavior https://youtu.be/crAjh8XWH4U

One thing to try, and I'm not sure if it makes a difference, is to place one of your additional red stepper drivers in the E1 slot so that all the slots are occupied.

That appears correct to me... Unfortunately I am all out of ideas on what could be the cause... Maybe Makertech can help you further. I will post a video later of what the correct behavior should be when you send the G28 and G29 commands.

Please post a picture of the main board you have as it is now.

Last print seemed to be significantly better than the others, but printer still needs a lot of work. I don't trust it to print anything taller.

Ok, revisit Step 6 and verify the following: • When running the TMC2208 drivers you will also need to invert the motor directions for the axes that you have them installed on: • Scroll to line 1067 (File -> Preferences -> display line numbers) and set as shown if that axis has a TMC2208 driver: • INVERT_X_DIR true • INVERT_Y_DIR true • INVERT_Z_DIR false The E1 and E2 should remain false since you do not have TMC2208 there.

Even if the red light turns on, that just indicates your probe is functioning, does not indicate that your arm is level and square with the bed. Saving the positions comes in at Step 23, after you've figured out what your Z offset is.

The included PLA was brittle for me from day one even though it was vacuum packed. Makes me unlikely to buy filament from them.

That is the correct behavior for the autoleveling. The probe moves all the way to the front corner and then will move across and probe a total of 20 points. The Probing Failed is because your Y arm is not level or square with the bed. Get the arm as straight as you can and try it again. Keep adjusting until the probing works.

Can you post a picture of the screen?

Wherever you don't have the TMC stepper drivers, you need to have the A4988 (red) drivers. Keep in mind that those are installed in a different orientation, as stated in the manual. Those red ones will keep all the jumpers in place on the mainboard (not UART). It should be on line 417, not sure why yours is line 420. Maybe try re-downloading the file from Makertech. https://github.com/Makertech3D/AXIS/archive/master.zip Step 4, that's ok, tmcstepper was updated since Makertech made the build manual. I actually have version 0.7.1. Unfortunately I cannot diagnose why you're unable to write the firmware to the board. I would try again after making sure you have the correct one downloaded from Makertech. Maybe you can find more help here as well: https://marlinfw.org/docs/basics/install_arduino.html

@Lau vdK so I kept all 5 TMC on the board, I still receive the error in Pronterface for the E1, however the 2nd extruder still works. I also occasionally see a "TMC Connection Error" on the screen, but again, all the motors function just fine.
