Mach4 General Discussion / Re: Homing & Limit Switches
« on: October 08, 2018, 01:30:35 PM »
I had already done that.  I ended up changing my settings for my limit switches so they were just homing switches.  After that worked a couple of times I reset the homing switches back into homing and limits like I had originally and it worked.  Until this morning and I had to do the same thing again.  And to add further to my frustrations the Mach 4 wouldn't recognize the ESS for configuration.  I rebooted, reloaded and reset.  Finally I just set the switches to homing only.  After I had it homed I set the switches to limit.  Almost feels like there is a bug in the software.

I finally installed a new BOB to my ESS and increased the inputs.  I did this about three weeks ago and everything worked great.  My homing switches act as limit switches for X-, A- and Y- while the homing switch for Z was +.  Like I said, it was working great.  It would square my gantry and stopped if I hit a limit.  My sequence for Ref All Home is Z+, X- (A- Slave as well) and finished with Y-.  Today when I fired it up and hit Ref all home, it limits out on Z+ and shuts down.  When I do and axis override it homes to X- and limits out at X- and says referencing complete.  I am using Mach 4.  I am almost sure I didn't change a thing.

Any thoughts?

I looked at Warp's link to BoB's. https://warp9td.com/index.php/bob-vendors#GeneralPurposeBOBs.  There are a lot of less expensive solutions.  At least I have a direction now.  Thanks for your help.

After reading your post, it appears that changing to the MB2 might be the way to go.  I am fairly new to CNC design and especially the electronics, but if I use ports 2-9 for a total of 8 additional inputs, there isn't room on the C11.  The C11 only has 5 inputs, so I don't know think that could work.

I have a fourth motor that is slaved which I am trying to home.  I have already tried the in series connection and didn't care for the functionality.  With the fourth motor and separate switches, I found I was out of short inputs.  With an additional BOB, does the the ESS communicate with the original BOB to control the motor output?

I have an ESS smooth stepper and C11G BOB.  How do I create more inputs to accommodate that many switches?

We are good to go.  I set the com jumper exactly how my documentation showed and it was wrong.  Life is now complete. Thanks a million.

Success!  But my motors X and A are working opposite.  Should I no have the A reversed when it is a slave?  They need to run in opposite directions.

I will, but if it's safe I'll try switching the com jumper to 5v first.

Ran G0 X5 and the LED for PUL- lit on both X and A axis (A is slaved to X in reverse).  Ran G0 X-5 and Pul- and Dir - lit. The Pul- wasn't near as bright as the Dir-.

Should the jumper on the BOB be set to com=gnd or com=5v?  My documentation from my supplier says set to gnd.  Would it damage anything to try setting to 5v?
