Machine: k40 custom (working area 1000x1000 2 nema 23 for y axis 1 nema 23 for x axis 4 nema 17 for z axis)
Board: cohesion3d with external stepper driver tb6600
Firmware: _Smoothie last upgrade
Problem/ Question: losing step/unaligned between cut and engrave
Hi to all I have this issue between fill scanning and line cut when i scanning at 0°(the lines are horizontal) so I had looking for mechanical desalignament, motor break, or the tension of belt but is everithing ok, so my problem probably is eletronic, or firmware parameter.
I have increased the voltage on motor, and I change the microstepping on the external drive but everything is the same.
I have a great improvement if I increase the line interval in the lightburn fill option but the resolution on a photo is very low
and finally I have change the direction of scanning(in vertical) and also with great resolution I have a good result
I can scan a photo or image perfectly (in vertical) but i need to have also a perfect scanning in horizontal because i need to engrave a vector image and in this situation I have a losing step
so i’m looking for backlash compensation in scanning offset adjoustament but when i try the scan is perfect, there isn’t a difference between the lines
help me please!!! it’s like if the y axis motors can’t make the small and millesimal movement in the same direction (I have 2 nema 23 with 2 external drives for y axis and 1 nema 23 with one external drives for x axis)
thank you all
