General Mach Discussion / Re: Unable to limit feed rate on Z axis..What am i doing wrong?

« on: July 31, 2020, 03:04:55 AM »

Alright the issue is back. Sometimes it will work on one line of code and not work on another line in the same program.

Mach3 is sometimes limiting the Z axis motor to the speed in motor tuning and sometimes not.

I sure am glad i paid for this buggy pile of ********* with no support.

It's understandable and I suppose you have to blame somebody but in your case Mach3 is just acting as the Motion Planner the actual and true control of your machine is all handled by your Langmuir Motion Controller.

EDIT; Additional information.

I have the Z axis set to 50ipm.

Reduce your Z axis Velocity in Motor Tuning to 39 and save the change.

My neighbour has just taught his dog to fetch cans of Beer.  It’s no big deal really except he is getting them from my refrigerator.

Hi Lawrence,

Sorry but I do not have the SainSmart board so cannot test your idea.

General Mach Discussion / Re: Cutting a Circle - Figures don't add up!

Unfortunately the 'Wiki' was terminated when the forum was re-designed for Mach4 and all that is left nowadays is the archived fragments.
Perhaps check out the Mach2 Customisation manual - that may have some more comprehensive details; https://www.machsupport.com/wp-content/uploads/2013/02/Mach2_6.11_Custom.pdf

As you say, Mach3 is 'as is' and as far as I can see, that is the way it will remain.

I'm sure that once I can get more than a blank screen from the Wiki link many of my questions will be answered

Many thanks for reporting back with the solution Cbert10, I am sure this will help others in the future.

General Mach Discussion / Re: Simple radius cutting - isn't !

« on: July 21, 2020, 01:15:18 AM »

I started using Mach when it was Mach2 and by then CAD / CAM was the way to go. From then and up to the time development on Mach3 ceased there had always been issues, reported on the forum, with cutter radius comp. From memory the usual problem was insufficient clearance at the lead-in but over the years many revisions were made regarding G41 / G42.
As mentioned earlier CAD / CAM calculation incorporating the tool radius to adjust the toolpath not only made life easier for the likes of me but it also relieved Mach of the additional calculation when creating the trajectory. Everything worked better.
I would not want to go back to driving a truck without power steering and I would not want to go back to using G41 / G42 although, as you say, they are not actually obsolete - it is just that I have moved on.

I'm beginning to think that 'Tool compensation' is not the way to handle 'Pocket' or 'External' cutting 

Cutter radius compensation used to be the way all Gcode was used but things move on and affordable CAD / CAM software took over making it all so easy.
