Hi tere!
I have a milling machine runnign Mach2 under XP for years. The PC was stolen so I purchased a new one, XP is no lobger available here so I bought Windows 7 starter
I installed Mach3 using the Vista instructions I found on Mach´s site. Everything owrked well, for a while, and then the motors started to loose steps and make strange noises.
It does not happen all the time. If I start Mach3 and do some jogging only, it works. But after I load and execute some g-code the problems start again.
I tried to swicth Mach3 versions, installed aditional LPT boards, change ALL parameters. It improve but the problem allways happen sometime.
Is Mach3 compatible with W7? Do I need a special version? Do I need to buy an XP machine?
Please help!
Thanks in advance

One question more: can I run Mach2 under Win7?
Thanks!

Yes, Windows 7 works great with Mach. If you want to use the parallel port then you must use the 32bit version. If you are using a SmoothStepper than you can use either 32bit or 64bit versions.

Thanks a lot!
What can I do? try another PC? another motherboard brand? Is Win7 starter 32 bits?
Thanks again!

Run the driver test and see what the graph looks like, if its not great then you could maybe try some of the optimisation ste[s detailed on the downloads page. They are not meant for W7 but probably a lot can still be done.

Driver test shows a half green bar with EXCELENT legend on it. Is it ok?

Does the line look smooth or are there large spikes every now and then?

No visible spikes, may be some pauses in the display, very shot. THANKS!

Should be ok then.
Is there any power saving options, maybe in the BIOS? Try turning them off if there are.

Alex,
Gene here in Texas........
I have been having what sounds like the same problems that you have with Windows 7 32bit running Mack3. The only way I can get smooth movement out of my motors is to run the velocity down around 100 and cut the feed rate in half. Please share the information on the changes that you made to your system and the 'bios'. I have run out of ideas. Please read my post under "Gene8522".
Thanks in advance for the help.
P.S. Don't look for Hood to come to Argentina until after he comes to Houston for the best steak in Texas.

hi, it´s me again
I am facing the same problem with another PC and I can´t make it work changing BIOS parameters.
When I load Mach3 everything works great. After I run the first Gcode the problems appears. Motor rattle in every axis.
I found a very strange solution, it si to deactivate the toolpath graphic display. I unchecked all options in the toolpath display settings and it work a lot better, near flawessly
I think the problem is related to the graphic subsystem of win7. I tried in using an external graphics card but it is exactly the same result.
Any tip?
Thanks in advance
