Hello! I’m trying to configure Klipper for this printer and I have this problem with the Z axis. I can’t adjust the travel. I ask for 10 mm of travel and it just moves 4 or 5 mm. This isn’t my first contact with Klipper but I am new in this maner. Can you help me? Thanks!
The board doesn’t have jumpers for the micro stepping and I have used this board in other projects without any issues.
Tried changing the current to the steppers and still no change, and yes that is the printer. I was willing to built a Voron 0.2 but it is a bit expensive so I choose this one.
Microstepping in Klipper does not affect the movement distance as set by rotation_distance
Side note on the board:
Due to the limitation on 12V and the used drivers the overall performance of the board is quite limited. Not sure if it is worth investing into it.
I did lower rotation_distance to 2. Gives this error:
MCU ‘mcu’ shutdown: Rescheduled timer in the past
This generally occurs when the micro-controller has been
requested to step at a rate higher than it is capable of
obtaining.
Lower your microstepping to 16 and if new issues arise please always post the klippy.log as well.
This error almost answers your second question:
This board has several shortcomings and I’d personally would not use it in any printer today:
12V VCC will severely reduce the steppers dynamics and acceleration capabilities (same is true for the heating elements like extruder and bed)
The used drivers are very simplistic and far from the fine-grained control modern drivers are offering
The used MCU is very weak and you can easily get errors like yours above. This error is quite rare these days, since such weak boards have almost vanished.
This is a Anet A8 era board and back then it might have been a nice option.
Lowering the microstepping worked but still didn’t travel what I asked. I leave here the klippy.log if you want to take a look at it. And could you give me some guidelines on how to interpret this log. klippy.log (166.8 KB)
I was afraid you were going to say that! And a very good explanation of why I should by another board, you really know what you are talking about! In your opinion what is a good board to by? Thank you!
This somehow makes no sense as 0.09 can never be a valid lead-screw. Are you sure you got it correct, i.e. measuring and calculating?
I cannot really comment on this one. Just my gut feeling is that there are quite a few issues reported around this board, but it may well be due to its popularity. From its general setup its a nice board.
I measured it again and it gave me 1. The near value is 1.25 which gives the rescheduled timer error. I lowered it until 1.48 and is almost there but not yet. What do you think?
