    Viper 200 Error deviations

    I have Viper 200s driving a 3 axis Bridgeport mill. The videos explain what I'm seeing under two different conditions. Do the really tall error spikes look expected? Are there any other general...
  2. Re: C11T board - spindle 0-10v output wandering and causing inconsistent spindle spee

    Arturo,

    Checking the voltage output from the C11T 0-10v was where I initially found the varying voltage problem while also listening to the spindle to make sure the voltage dip correlated to the...
  3. Re: C11T board - spindle 0-10v output wandering and causing inconsistent spindle spee

    Thanks for the speedy reply, Arturo. I was grounded on the wrong end but I just switched it around and the problem persists. I guess I shouldn't be surprised as I think it was running OK for a...
  4. Spindle output voltage (0-10v for VFD) wandering - causing inconsistent spindle speed

    Howdy,

    I have Mach3 (on a dedicated non-internet computer) talking to a C11T via a USB SmoothStepper. Things were fine for a good while but I recently noticed that my spindle speed began to be...

    Howdy,

  6. Re: Mach3 lowers Z and crashes tool at tool change.

    After spending a good while digging around, I stepped through the M6End.m1s macro and found that it was causing the z move. I purchased this machine second hand and I suspect the previous owner...

    Re: Mach3 unexpected plunge after tool change

    Did you ever get this one figured out? I may be having the exact same problem.
  8. Mach3 lowers Z and crashes tool at tool change.

    Hey guys. I'm having an annoying problem during a simple tool change. At the "T2 M6" line, I insert the tool into the spindle and press "cycle start". This causes the Z to slowly extend all the...
  9. Re: Can't connect serially to one of my three Viper 200 drives

    Rats... sorry about that, Larry. Damn customs. (nuts)
  10. Re: C11T Breakout Board Power, 5v and 12v. Did I get it right?

    No problem at all, Arturo! I appreciate that you took a few minutes to help me out. I have found the documentation on how to wire my drives up, and that all makes sense. Given that I had been...
  11. Re: Can't connect serially to one of my three Viper 200 drives

    You, sir, are a gentleman. I'll ship it out via US Mail this week per the info on this page. Thanks very much.
  12. Re: Can't connect serially to one of my three Viper 200 drives

    Thanks very much for the reply, Larry... All of the soldering looked fine, nothing is missing, and there were no foreign objects shorting anything together that I could see. I did do some checking...
  13. Re: C11T Breakout Board Power, 5v and 12v. Did I get it right?

    Thanks for commenting, Arturo! Instead of trying to type a description of why I'm still confused, I decided to make a short youtube video to explain it more effectively. ...
  14. Re: C11T Breakout Board Power, 5v and 12v. Did I get it right?

    OK, I think I have this figured out now. The tl;dr is that I think I have the wiring correct as shown in the picture of my original post.

    Here's the nitty gritty of why I think I have it correct....
  15. Re: C11T Breakout Board Power, 5v and 12v. Did I get it right?

    Thanks, john-100. I see what you mean about where it says "these GND terminals are common to PC GND". I suppose I didn't immediately recognize that text as instruction to supply PC +5v at that...
  16. C11T Breakout Board Power, 5v and 12v. Did I get it right?

    I found the documentation slightly unclear regarding exactly which power connections should come from the PC vs. which should come from my dedicated machine power supply. Best I could figure out,...
  17. Can't connect serially to one of my three Viper 200 drives

    Like the post title says, I can't seem to connect to one of my three Viper 200 drives but can connect to the other two without issue. Also, I was able to connect to this drive a few weeks ago and...
  18. Re: Bridgeport R2E3 delima, 220v VFD 3 phase Versus 220V Single Phase

    Hey Ronderkis... Sorry to resurrect an old thread but I'm investigating the same thing as you were dealing with. I have an R2E3 that is already retrofitted but was running at a shop that had 3...
