Exact Stop vs Constant Velocity in Mach3

In this video, i describe the machine setup differences in Mach 3 using exact stop vs setting up constant velocity. Many folks have problems with corners being rounded in Mach 3 and it is likely due to the CV settings on the General Configuration page.

Finally a great visual explanation! Thank you so much!

Finally someone that explains things that a person that's not an electrical engineer can understand.

Exactly what I was looking for! Thanks!
My corners were rounded and I couldn't figure out why. Now I know...

This is very helpful thanks! I always wondered how to make my cnc cut similar to spendy machines like thermwood. They always nearly stop at angle cuts, and seemed to not be as jerky as most cncs. Exact stop seems to be what theirs are setup with

Hi,

I would like to clarify this..!!!

Suppose I have downloaded a fresh copy of Mach3 from the Official website and configuring for a CNC Router Mill.

Starting Over with a fresh Software Copy from official site always gives that warm and fuzzy Feel....Na ? LOL

Any recommended parameters other than these?

1) setting up the Steps per Unit is easily done by inbuilt calibration option

2) Setting Velocity and speed can be fine tuned by trying multiple combination of values and test runs until we feel comfortable

3) The Configuration of Soft Limits and Limits Switches and Homing switches are optional as We can live without them.

Do You recommend any additional parameters to be set up for the smooth operation of A CNC Router ?
I have seen Many additional parameters tweaking by People Such as-

Constant Velocity/Exact Stop
Debounce
Frequency Of Communication
Look Ahead settings

Are these settings that Important?
Do You have any inputs to give on them?
I want to perform it like a Smooth CNC Router which Can Carve some smooth Wooden Legs and Figures..!



I am going with the most Common standard and Conventional Configuration which is -
4 feet X travel and 8 Feet Y travel and May be 1 feet in Z travel, Just like the Standard Convention.!

Seems like the same difference obtained by using G64 instead of G61 instructions before your cutting instructions in the G-code. (Maybe the Mach3 interface is doing just that?)

In the video there is a glimpse of a cut where the outside cut looked correct BUT the inside cut line has cut the corners off. This is the exact problem I’m looking to fix. Any ideas how??

2mm distance tolerance is huge. I think mine is set to 0.001", i e. 0.025mm. Mind you, I'm machining metal, not wood, but still.

А какой вариант был максимально похож на модель???

[Abhisphukan]

Can you tell me which spindle you are using?
