General Mach Discussion / Re: new computer can't jog faster than 50 ipm?

Craig, Thanks again. Do you see any issues running a touchscreen with your set up? Or a similar system?

General Mach Discussion / Re: Speed of stepper motors

« on: November 27, 2015, 08:52:33 PM »

Yes in the inbox was G80 and I changed it now to F1200

The axes seem to move faster for one step, but if i want to test it for more example 10 steps
the motors start moving and then I get a high sound and the motors stop moving
Could it be that i have now a too high velocity?

This is called stalling. It can be caused by a few things, one of which is too high of acceleration.

I believe Mach prefers the EPP setting in the BIOS.

Craig, Thanks for the response. I dont understand a lot of what you said but it does seem to confirm my suspicion. There are differences in performance.

Though I do have a few flavors of SS, USB and ESS. My thought is that if the computer is causing the issue, while will it not show up via the SS? Trying to quantify just what is responsible for stepper performance is difficult. It isnt as simple as meeting the minimum requirements for Mach or adding RAM or graphics card.

I have had great results from a few PC's over the years via a PP and would like to pursue that avenue before any other approach even if ancient by todays thought.

I see you and a few others are running Atoms or mini itx systems (computers are not my forte either so excuse my terminology if I am off). From what little I can tell, They seem to have integral graphics cards and parallel ports. You dont have any issues running Mach with them? What kind of specs would be required? I wouldnt mind building one. There has to be a youtube video on how to do that! ;-)

  Though I am a native Texan, my mothers family lived in Brownsville. I go there every year for a reunion. Many relatives in and around Memphis area. Anyone named Taylor or Thornton ;-)

   I am glad to have stumbled upon this thread. I too have experienced vast differences in my steppers performance with a simple computer change. Computers with very similar specs. I have a video where I was testing my mill during a warm up routine and 300 ipm split on the 3 axis simultaneously. I am lucky to get 60 out of any single axis now.
   Didnt seem to really see a solution here but I do know some lower spec'd PCs have given me some higher machining speeds. I was thinking I was having a machine problem only to disconnect the stepper and find the screws spin freely.  The stepper was stalling. I do have a few SS's but that isnt the point.

Thanks for sharing and I am glad you are doing well. Just out of curiosity, what part of TN are you in?

PoKeys / Re: 57E stuck in recovery mode?

Never mind. I reloaded everything and it worked fine. Just needed a firmware update.

PoKeys / 57E stuck in recovery mode?

« on: October 01, 2015, 05:21:04 PM »

I am not sure of what I did. I just downloaded M4 and the Pokeys plug in. I also downloaded poblocks. I can see the 57E in pokeys configuration window. All it says in recovery mode. It doesnt seem to recover though. Next step?

   Bravo! That was a beautifully done series.
 I believe I am brave enough to attempt a revisit of M4 soon!

   I do pose a question on video 3 about the simultaneous homing that occurs at 13:50. Z should have moved first but didnt.
