Sorry if it was not clear, I redraft it, thanks for being interested.
Hi all.
My name is Miguel Angel Amoros, I'm from Valencia, Spain.
I have a milling machine and a diode laser working perfectly with mach3.
To put the laser tube into operation, I looked for a lot of information on the internet, and until I found the posts Tweakie published on various forums, artsot, Hungarian, and others, I could not get the laser to work perfectly, in the end I did it work with the M11P system plus the virtual axis B, and now works great.
I have also been able to take pictures with the Impact / engrave Plugin that work well, but I have built the hardware with MAX digital potentiometer to be able to buy the Picengrave program, but this is where the problem comes from, I have done tests (with demo mode) and finish the photos burning excessively, and when the laser stops instead of going out, it stays burning a lot in the 0-0-0.
Investigating I realized that the problem is that the MAX goes out of range and sends too much tension to the laser, I realized when the gcode finishes that it stayed with almost three volts when it had to be at 0v.
Then I realized that there is a problem in mach3 when it is in millimeters, I have configured the Z axis as they say in picengrave that is that the Z axis has to have 393.7 steps per millimeter, and it turns out that if I reset the MAX , putting in MDI G0 Z-0.3238 which is 50% value to calibrate the MAX on the screen I get Z-3226. obviously in normal jobs this does not matter, but to calibrate the MAX and its subsequent conversion of pulses to volts is a big disaster.
This I have not been able to ask in picengrave because I asked to enter the forum, but surely if you do not buy the software they will not let you enter. But of course, if this can not be corrected, I will not buy the software.
Why do I put a figure in MDI and another one appears on the screen?
