Can Mach3 go too fast??
« on: June 15, 2015, 05:20:24 AM »
I am having difficulties dialling in a new plasma cutter on my table, faults lead towards going to fast but everyone says the book spec should work perfectly.

My question is - Is there any way I could set say a feed speed of 1000mm/min in code and Mach3 runs it faster than it should?

What is the speed regulation method internally??

Thanks

HiYA Dave, as long as the machine is calibrated correctly as far as steps per. Mach3 WILL maintain its speed precisely. THe ONLY time Mach3 will vary is when the kernal spped may vary a touch from the defined kernal speed.

Defined = 25000
actual = 24900

Then speed will be off by  .004

(;-) TP
