OK, let's try again with the file re-named.

If you can post a copy of your Mach3 profile I'll have a look.

Jeff,
I'm having trouble posting the file, don't understand why I get this message when I try to attach my SmoothStepper.xml file:
"Sorry! There is already an attachment with the same filename as the one you tried to upload. Please rename the file and try again."

I tried several times and got the same message.

So...  ???

take a look at the last couple of pages here, it is about spindle set up with the SmoothStepper: http://www.soigeneris.com/Document/Warp9/Installing_and_Configuring_the_SmoothStepper.pdf

Hi Jeff,
I had already looked at that document, and all the others referenced in this forum for USB SmoothStepper spindle control, but it (and they) was (were) no help.
However I will re-read the last few pages and have another play, but I'm busy with other stuff at the moment so it might be a while before I can do that and report back.
Thanks for your help.

Cheers,
Dave.

Hi All,
I have been using my mill via the parallel port for years with no problem but recently fired up a laptop, to use a USB SmoothStepper.
All was fine under PP mode, I could enter the required speed and Mach3 would see the spindle index pulse and regulate the spindle speed according to what it was set to with the S command, speed regulation was very good (PWM mode).

On my laptop, I have the SmoothStepper with no BoB using Port 1 only - i.e., nothing connected to port 2 and no other connections.
SmoothStepper is connected directly to a Xylotex XS-3525/8S-4 stepper driver board. A Homann Designs Digispeed XL remains connected to the Xylotex board's break out screw terminals.
I am using Mach3 version 3.043.062 and SmoothStepper version 2.08.24 with V17fe.m3p file. I was using an earlier version of all but upgraded to those when I struck the problem described below - I still have the problem.

I copied my PP XML file to the laptop and set up smooth stepper with the plugin etc.
X, Y, and Z axes work fine and I can fine tune steps and backlash OK.

I can start the spindle and stop the spindle using M3/M4/M5 commands via a Homann Designs Digispeed XL using PWM and Mach3 displays a speed when the spindle is running.
However if I set the speed with an S command, to say 500rpm, when a M3/M4 command is executed the spindle immediately ramps up to top speed (e.g., 1700rpm) and stays at that speed.
It doesn't matter what speed I enter with the S command, the result is the same.

I can see rpm's in Mach3 but they are not stable.
For instance, irrespective of what speed is entered in Mach3 I get a constant spindle speed of 1700rpm (verified with a second spindle sensor/display) and I see the Mach3 display of 1700rpm intermittently fluctuate upwards by as much as 600rpm momentarily, the second rpm display remains constant at 1700rpm.
I have tried two different spindle sensors with Mach3 with the same result.
I've tried different Ports/Pins, Motor settings, and Spindle settings in Mach3 but nothing I do rectifies the problem.

Here are my current settings:
Motor Outputs Ports / Pins
X. 2 / 3
Y. 4 / 5
Z. 6 / 7
Spindle. 14 / 17
Step/Dir Port 1. Dir - active low, Step - active high

Input Signals Ports / Pins
Probe. 1 / 12
Index. 1 / 15
EStop.2 / 2
All active high
Note: I could not get Estop to work on my original PP settings of port 1 and pin (2?) - (I can't remember what it was set to), so why it works on a port 2 setting when I don't have anything connected to it is a mystery!

Output Ports / Pins
#1. 1 / 1
Active low

Encoder/MPG's
MPG #1. 1 / 10 and 1 / 11  counts 4/vel 100
I have not tried using the MPG device with SmoothStepper yet but it worked fine with those settings on PP.

So, can anyone put me out of my misery and tell me what I am doing wrong?

TIA,
Dave.

Share Your GCode / 9x20 lathe, reverse tumbler bracket Gcode wanted
« on: January 25, 2015, 12:32:40 AM »
Hi All,
I have a 9x20 lathe and want to make a reverse tumbler for it.
I had the Gcode to cut the bracket many moons ago (to use when I got around to it...) but it has disappeared from my files.
Has anyone got Gcode for the reverse tumbler bracket?  ???

Many thanks,
Dave.

Thanks Dan, I've downloaded it, I'll hang onto it for later. ;D
Cheers,
Dave.

Hi Dan,
You mean this one? (2011-05-21    PlugIn: SmoothStepper_v17d.zip)

It's not available for download anymore.

There are only these three available: 2011-10-30    PlugIn: SmoothStepper_v17efb.zip,
this: SmoothStepperUSBDriver2.08.02.zip
and this: SmoothStepperUSBDriver2.08.14.zip.

Anyways, it's going to be a while before I get my workshop operational and mill reinstalled and by the time I get round to it things may have changed so I'll keep my eye on things.

Many thanks,
Dave.

Thanks Dan,
I've just been looking at the plugin versions and info on the SS web site but I'm still not clear what plugin and Mach3 combo I should use. There is still a bunch of red text saying that they have discovered a problem and that we should use the Dev versions of Mach3 rather than the lockdown one.

So I assume that I use this plugin (SmoothStepperUSBDriver2.08.14.zip) with Mach3 Dev R3.043.059? Incidentally the Mach downloads web page lists the SS plugin as 1.19.********* - needs updating.

Many thanks.

Thanks Dan,
So was the fix in Mach3 or was it in the SS?
As I probably have a very downlevel SS  :( I'm hoping it's a Mach3 fix.

Cheers,
Dave.

Hi all,
I've been away from machining for some years, moved house/state and all, and just thought I would get back to the forum.
Anyway, without trawling through masses of posts, was backlash compensation ever fixed for the SS?
I've checked the build logs for the latest lockdown release of Mach3 (what, no Mach4?) and didn't see any mention of a BC fix - or is the fix meant to be in the SS?
What's the latest on BC, guys? I still have my (unused) SS sitting in a drawer somewhere.

Thanks.
