Windows 7 with USB Motion controller
« on: March 09, 2021, 05:32:27 AM »
Hi, I'm not sure if this is the correct way to go about this but I have an issue with a USB Motion controller with Windows 7. After I boot up Win7 and then open Mach3, although I can jog smoothly any attempt to run Gcode just makes the motors stutter and miss steps. If I wait awhile and re-open Mach3 all works smoothly. Is there some way of knowing when Windows 7 has settled down or some settings that can be changed to improve this. I bought the USB Motion controller as a back up so that when my old XP PC dies I am able to move forward without too much delay. At the present time have the motion controller set up with a couple of spare stepper motors and drivers just to evaluate and to get used to its setup. Any help to make the system more reliable would be apprciated

Unfortunately, due to their Pirate License distribution, this forum does not support the use of Novusun products.

I understand that Novosun may distribute Mach3 with their product but I am not using this distribution ,  I bought Mach3 long before and I am asking for some help. I guess this issue is also prevalent on other USB motion controllers.

I have not seen this particular problem reported on the forum with any other supported USB motion controller.

My suggestion is that you consider using an Ethernet connected motion controller (such as the Warp9 ESS or the CncDrive UC300ETH / UC400ETH) which has plugin support for both Mach3 and Mach4.

Thank you, for your reply. I am rather loath to just throw away the Novosun controller as i bought it in good faith as a backup in case my Windows XP PC dies. In all honesty in view of the issue with Novosun and Art Soft which I fully understand I should probably have avoided both issues and gone for the smc5-5-n-n or similar.

I'm retired and this CNC is just a hobby and I am keen to keep the budget in check.
