Mach4 Plugins / Smoothstepper USB plugin

« on: November 24, 2016, 12:42:50 PM »

Does anyone know when there will be a Mach4 plugin for Smoothstepper USB? They've been working on it for a couple of years now, but there's no sign of a release date. I'd really love to get started on Mach4.

FAQs / Steppers stutter or stop when using computer

« on: April 02, 2011, 11:28:03 AM »

I'm sure a similar question has been asked before, but I can't find it when searching.

So the problem is this: Whenever I do anything on the Mach3 computer, be it opening a document or inputting a new Gcode line in MDI, the steppers stutter or stall. They stutter regardless of kernel speed and feed rate, and at higher feed rates they lock up. When I leave it completely alone, it seems to do fine.

The computer is as follows:

Asus P5V-VM DH mainboard (VIA P4M890 chipset)
Core2 Duo E6300 (1.86 GHz)
On-board LPT port
On-board VGA or ATi Radeon X1300

I switched from the on-board VGA to the Radeon based on other posts, but it made no difference.

The signal goes through a KelingInc KL-DB25 opto-isolated breakout board and into PacSci 6410 microstepping drivers.

Any tips?
