SmoothStepper USB / Re: ESS and poor motor response

Don't assume that the .xml file has all the correct settings for your machine. The CNC Routerparts .xml file contains settings that work with their machine, not yours.

I'd recommend starting with a completely new profile, and setting up everything yourself correctly.

If you want your machine to run correctly, you're going to have to learn how to do it.

The motors now move faster and smoother except for the first second or two on the Y axis. It still has a grinding as it starts and stops but runs better back and forth than it did before.

It sounds like you may have incorrect steps/unit settings, and acceleration and velocity settings that don't work with your machine. Acceleration and velocity need to be set using a trial and error process.

My DRO for X,Y & A are red and will not go to green

This sounds like the machine is configured to possibly use home switches, and you don't have any?

All of these issues can be from using an .xml file that doesn't match your machine.

General Mach Discussion / Re: Where are Mach3 settimgs held?

Yes, if you want to work in inches, then your native units should be inches.
If the native units are set to mm's, then any setting in Mach3 should be in the same units.

General Mach Discussion / Re: newbie - How to move to and entered value?

« on: May 31, 2015, 09:05:44 AM »

Use MDI.

If you want to move to X5 Y5, just type the following into the MDI window:

G0 X5 Y5

When you hit enter, the machine will move to 5,5.

G0 is modal, so you don't need to type it for subsequent moves.

Just X5 Y5.

Not publicly available.
From the Yahoo Group:

is there a change log anywhere?....................


The SVN server has all that data.. I don't think we put that out for public consumption. some of the comments are a little colorful LOL.

Thanks

What size are the other motors? What drives are you using? If you have a Nema 17 on the Z axis, than I can't believe that you'd need 12.5 amps. 7 amps should be plenty, but I'd need more information.

Are the acceleration and velocity settings the same on both PC's? And no settings on the drives have been made, but just switching PC's makes the difference?

Mach4 General Discussion / Re: G31.1, G31.2, G31.3 working?

ger21,

Can't see any recent related postings by Brian on the Yahoo group.  Can you provide a pointer please?

Thanks all.

The posts were about point cloud probing, titled Mach4 Swap Axis on 5/26.

Well shoot, we can code it without G31 theoretically I think. G31 just makes life easier on us by automatically storing the coordinates in a file upon contact, then retract and incrementally jog by say 0.001, move in a pattern by same amount until contact, write to file, retract and repeat unto ~= contact while moving across a user defined coordinate plane. How did Mr. Barker do his probing video on youtube with Mach4? Bet you he just coded a script for execution or maybe that's why we only see a short video clip...

Brian posted a probing script on the Yahoo group either yesterday or the day before.

Are you using the same profile?
