I started my first 2-axis CNC project (i’m a newbie). I don’t want to make a plotbot but a 2 axis, hot wire foam cutter. I’m using the old software version (windows 32) of makelangelo and it partialy works. I have the arduino mega 2560 R3 and 2, 28BYI-48 steppers with the uln2003 drivers. I want to make a simular solution as the costycnc.
The steppers are moving but Always together, not only x or only y, it is usual for the plotbot but it’s not the goal for my cutter. Do you know anybody who achieved this? Or do you know if there is software what achieves my needs?
I found many solutions with other stepperdrivers/shields or GRBL solutions, but not with the 28byj-48. I realy hope that someone can help. I’m not a java programmer (and have no intensions to become one).
Thanks in advance!!
Post moved to CNC+Arduino forum with the other hot-wire cutting threads.
When you say they dont’ always move together, do you mean
(a) the x and y motors don’t always move together
or
(b) the x motors on each end of the wire cutter do not stay in synch or the y motors do not stay in synch(a) should not happen anyhow. For (b) I would try physically wiring both X steppers to the same driver. then any step command MUST go to both X at once. Repeat for Y.
If you post a schematic picture of your wiring and your source code online then people could offer suggestions.
If you don’t have any code, how are your motors moving?
The RAMPS shields are 12v. That could be doing awful things to your 5v parts.
