Mach4 General Discussion / Spindle Issues
« on: November 25, 2020, 12:22:11 PM »

I've got Mach 4 set up with the ESS Smoothstepper. 've got build 4517 and ESS build 260.
I created a new profile from the MachRouter with the wxRouter.set. I set everything up and encountered an issue with the VFD spindle.

If I try and start the spindle with the MDI or G Code using M3 it starts and then immediately stops. The green M3 button lights up. If I click the M3 button the green indicator goes out. If I then hit the M3 Button again the spindle starts at the correct speed as per the MDI M3 command entered.
Also if i start it with the MDI and change the spindle speed percent the spindle starts !!
Entering M3 or M5 then freezes the console.

I created another new profile and set up the ESS and just set up the spindle, it worked fine ? I then entered the rest of the inputs and outputs and it started the odd behaviour again.

I'm totally baffled as to why entering the rest of the settings would make the spindle behave in this manner, any ideas ???

Thanks Craig, Very helpful information.

I've now got it working.

Am I right in thinking that when the drivers alarm for a position error they stop and need a power down to reset ? If that's the case I'd lose my reference anyway, or am I misunderstanding something ?

I've got servo's from DMM with the DYN2 driver. I'm using an ESS with a C25 breakout board. I've got the motors set up and working fine.
In the documentation I got sent it tells me to use Pin 8 of the DMM Driver connected to an input of the ESS to trigger an Alarm.

I've connected the Pin 8 Alarm output to Port 2 Pin 9 of the C25. I've set the pin to Active Low and named it MOTOR ALARM in the ESS pins config tab.

I'm not sure what to set after that to map it to an alarm in Mach 4.

Could someone please help me out ?

Got servo's from DMM only to find the same issue with those ?
Finally found it was my laptop that was a bit to old for the job, used my new laptop and they work fine, even the closed loop one.

Can't believe how good the servo's are, quiet, cool and can go way faster than I could use :-)

Thanks again for the reply.
I'll have an experiment with power supplies I think and see how good I can get my current motors working.

I've also asked DMM for a quote to replace my X and Y axis motors, might be a bit to pricey for me though.

I finally got the C10 BOB for Port 1 of the ESS. This has not made any difference to this issue.

The motor is strong up to the point when it just stops, no loss of torque, so it's definitely just not responding to the faster signal.

On the plus side 'Fast to Buy' gave me a 70% refund and let me keep the motor and driver becaus they could solve my issue, so i've used it on my X Axis anyway as it is a lot smoother and quieter and than the open loop drives.

I'll have to post and see if anyone has any recommendations for motors and drivers to use on the ESS.

Carl. ;)

Thanks Craig,

My drive is not labelled as Leadshine, though it looks the same.

I'll sort the rs232 leads out to check the parameters with the Pro-Tuner software, if it works.

I'm going to sort my wiring as well as I've daisy chained the supplies to the drivers, in fact I'm going to just run this drive on it's own with the ESS without the rest of my hardware to try it.

The set up time for the step signals is 2.5us and the current requirement is 10ma, so the ESS should be ok if I read and understand that right.

Anyway i'm getting the barbie out for easter Sunday, unbelievable for Manchester in April !!

Thanks for your help.

Thanks, ive ordered a C10,  dont know how long shipping will take. I'll update when its arrived and tried out. Im only using the opto's on the inputs for the 36v switches.

Thanks Craig,
I think that may be my issue !!
I couldn't get a BOB in the UK when I first built my machine so I made my own Opto pcb for the inputs for 36v Inductance switches, the outputs are direct to the ESS. I'll have to see what I can buy now or I need to look at output buffer design to make my own  :( :( :(.
