General Mach Discussion / Re: Re: Problem with homing

I see you are using the ESS, have you updated the plugin since it last worked?

I  don't think so. I have been running v10hd since it was released.

I updated the last time to address the homing issue where the gantry would rack when the homing switch is enabled on the slaved (A) axis. I disabled the A axis homing switch in the configuration to allow the Y/A axis to home. The axis would home, but there was the possibility that the A axis could be slightly off from the Y axis. I would manually adjust the A axis to correct the offset after homing. Despite all this hassle, the table would home.

I'm running a PMDX-126 with an ESS board. I wired the limit switches for each axis in series and gave them their own input pin.

Is there a known good/stable version of the ESS plug in? I know development for the Mach3 plug in has been delayed due to the developer focusing on a release for Mach4.

General Mach Discussion / Problem with homing
« on: July 09, 2013, 01:20:56 AM »
I have a CRP-4848 that has been running fine in the past.  I tried using it this weekend and discovered a problem when I try to home the table. 

When I initiate homing the table, the Y/A axis moves backwards to the negative Y limit switches, the A limit switch gets triggered first and the homing procedure stops.  The console shows that a limit switch has been triggered.  When I look at the hardware signals it shows the A axis is triggered.  I have the Y and A set to home together in the General Config.  This has worked in the past.  I can back it off and try again, but I get the same result.  I don't want to disable the A limit switches since they serve a purpose to protect that side of the table.

I have included my config file.  I suspect if Hood looks at this, he'll want to see it  :D


I've been very happy with Alibre PE and Bobcad V25.  You should be able to talk the sales folks down to under $1000 total for both.

I have had the same problem with my CRP-4948. Ahren over at CNC Router parts suggested it was the CV settings. I haven't had a chance to investigate further. One thing I noticed was if I drop the feed rate down that the problem went away. You might try that.

I noticed l wasn't seeing a tool path either when setting up a surfacing job. I also noticed that my feed rate on vertical moves was zero in the generated g-code.

Both problems were fixed when I changed feed rate for plunges in one of the dialog windows. The original value shown for the feed rate looked like it was calculated from the tool input. Reentering the value caused both problems to go away.

I hate replying to my own messages.

I just noticed that if I Alt-Tab the configuration window pops up.  I don't know what could be causing this.

I'm running the latest plugin from Warp9 with Mach3 and whenever I try to access a config screen I am seeing long delays before the configuration window comes up.  The delays can be anywhere from four to ten minutes (or even longer).  Eventually the request window does appear.

I haven't tried all windows, but I have seen the behavior with the "Ports and Pins", "Home and Limits", "General Configuration", and the ESS plugin configuration window.

Is this an ESS thing or could it be something else?  I have only ran Mach3 in simulation or with the ESS plugin.

My system configuration is:

  I5 @ 3.2GHz
  16GB RAM
  nVidia 470
  Windows 7 64-bit
  Mach 3.043.066 (Dev version)
  ESS v10fb2

SmoothStepper USB / Re: ESS HOMING ISSUE
« on: August 19, 2012, 11:46:25 PM »
I'm trying to integrate an ESS board with a PMDX-126 on a CRP-4848.  Homing the X axis and slaved A axis is failing with either both axis stopping on the X-Home and the X axis continuing into the end of the axis and hitting the bumper, or both axis stopping on the X-Home, the X stepping off the X-Axis while the A-axis starts moving positively until the gantry is twisted.

My reading suggests there is possibly an issue with homing slaved axis with the ESS.  Any suggestions, hints, hopes?

I'm seeing something with my set-up that looks suspiciously like this thread, but it's with a new ethernet SS.  I was wondering if a solution was ever found?

My setup is a CRP-4848, ESS (V0), PMDX-126.  Homing acts very oddly if I enable the A-Home switch in Mach3.  Sometimes the X-axis will continue to move back and hit the physical stop or the A-axis will move forward after the X-axis moves off the X-home switch.  I do not have homing slaved in the General Settings.

Home works if I disable the A-Home in the Ports & Configs, but it won't square the gantry.



I'm new to Mach3 and I'll be using it with a CRP-4848, NEMA 34 electronics/steppers, 3HP water cooled spindle, Hitatchi X200 VFD, ethernet Smootherstepper, PMDX-126, PMDX-134, PMDX-107, and Gecko-201X stepper drivers. 

I'm a complete newbie to CNC and machining, and I've been lucky enough to get this far without making too many mistakes I couldn't recover from.  I'm about 85% complete and I'm starting on integrating the ethernet Smoothstepper and start testing movement.
