I need HELP!!!
I am running Mach3 on my DIY machine and after talking with them many time we can't seem to find out what the problems is. I have checked everything for tightness and all my connections. I run a program and at different points the machine makes wrong cuts. I have checked the motor tuning, controllers, ball screws and all that stuff still no answer. The guy at Mach3 said go to Vectric Forum and ask if there is anything in the software that will you to do "fitted curves or something like that". I am at a dead point......Please HELP!!

First, post a pic of what's happening, and the specs on all the components your using, and even a pic of the machine.

Generally, lost steps, are due to trying to run the machine faster than it's capable of moving. But, they can also be caused by a variety of things. Software would be last on that list.

Rapid changes in direction could do it also. Like in Z moves where the Z moves up to reposition then back down to the workpiece. Acel and Decel can help with that.

BUT - that's just a generalization.

You need to tell us more detail.

Pictures help a lot.

A youtube video is even better.

A good grounding system for your machine, controller, dust collection, etc. often solves issues that are puzzling and intermittent.

As Ger21 & Leo have said you need to provide a lot more detail & some pictures, there are so many different factors to take into account anyone trying to help without any more detail is just guessing. Have you posted on the mach3 forum about this or speaking to someone on the phone/email ? The mach forum is a helpful place but they are going to ask for the same sort of detail people on here are asking for :lol: :lol:
