We had an instance where a machine was cutting and the estop was pressed the rotation of the cutter acted like a cork screw and pulled the Z slide down into the job because the stepper motor de energised.
If the pitch of the Z screw was greater this would not be an issue.

The time taken can be calculated looking at the distance the tool travels in the program and the feedrate it moves per minute. The problem is the tool is not travelling at a constant velocity and any axis reversal causes the slide to have to decelerate to a stop then accelerate to speed again. Where...

Hi, The electronics you have are made by North East Electronics. Unfortunatley they are very old and now unsupported. :cry: Several people on the forum have replaced these and fitted Mach 3. There are several threads telling you how to do this. Someone else may have some other suggestions though :?:

MDF can be cast into multiple times. The ones shown have been just poured then sanded from the back. We are cutting some more today and I will upload some images. This time we have made a fill hole in the mould and G clamped a back on. It works great. We have also cast into model board and the mould...

The tuning value is used to take out backlash in the movement of the optics. The laser fires in both directions while raster engraving and any backlash in the system can be seen. The tuning value should be somwhere between 0 and 10. When a laser is supplied it will have been set so the backlash has ...

If you take the program with the problem and run it first without the spindle running. (delete the M03's) and check if there is any loss of position. If not add the M03's back in and try again. If still no problem then try while cutting. If you have coolant it may be a noise problem with the coolant...
