Galil / Anyone have older revision firmware for DMC40x0 controllers?

« on: January 10, 2020, 04:37:04 PM »

I bought a DMC-4040 controller off ebay.  I want to upgrade the firmware, but upgrading to the latest version has to be done by Galil, and they won't do it for us.  Does anyone have a prior version of the firmware for the DMC-40x0 they could send me?  Preferably the version immediately before 1.3?

Thanks.

CS-Lab / Anyone try the Arbah DSP drives

« on: August 01, 2014, 12:22:54 PM »

Hi,

I was thinking about ordering one of CS Labs Arbah DSP drives.  Has anybody tried them?  What did you think?

Thanks,

VB and the development of wizards / Sleep() doesn't work when called in Macro

« on: May 21, 2014, 09:13:41 PM »

Hi,


I am running Mach version 3.043.066.
I have a CS-Labs CSMIO IP/S.

I wrote a macro M301 that I want to use to turn on an air solenoid for one second.  The code is:
SetPulley(1)
Pulley1On = OUTPUT3
Pulley2On = OUTPUT4
DeactivateSignal(Pulley2On)
ActivateSignal(Pulley1On )
Sleep(1000)
DeactivateSignal(Pulley1On )

This works properly when I am in the vbscript editor, but when I call it from MDI, the output is activated, but never deactivated. 
Thanks,

Bill

CS-Lab / Does the CSLabs CSMIO IP/S do CSS?

« on: March 10, 2014, 05:57:27 PM »

I am retrofitting a lathe with the CSMIO IP/S with Mach3.  I've heard that Mach4 will to constant surface speed, but want to start using the lathe right away.  Will the IP/S and Mach3 do constant surface speed? 
Thanks,
Bill

CS-Lab / Should the IP/S sink current in the active low state?

« on: September 06, 2013, 10:28:22 PM »

The opto 22 output modules I was hoping to use are activated when current can flow from the opto22 logic control pin to logic ground.  Can the IP/S output pins sink current when in the active low state?  If not, what does happen in active low?  It only needs to be able to sink 12 mA.

Thanks,

Bill

I am considering using the ESS or a cnc cmm retrofit.  Anything I should know about?  Any suggested screens?

Thanks,

PoKeys / pokeys vs DL06 PLC?

« on: March 09, 2010, 07:32:36 PM »

Hi,

I have been doing a retrofit for way longer than I would like to admit and purchased an Automation Direct DL06 and all the necessary breakout hardware for doing a lot of the i/o on a vertical machining center with a tool changer.  I am just now getting to the tool changer and was thinking about maybe using the pokeys for the i/o instead.  It seems like it might be easier to program it with a brain or macro rather than having the plc handle some of the i/o and the smoothstepper I am using handle the rest. 

Any thoughts would be appreciated.

General Mach Discussion / Drive Reccomendation?

« on: February 08, 2010, 06:11:27 PM »

I am thinking about doing a retrofit of a gang style lathe that has 2 100 Volt DC servo drives rated at 6A continuous and 36A peak current.  I was thinking of doing it with a smooth stepper and replacing the drives.  Does anyone know of cost-effective drives that would work well for this application?  I am hoping to find something that has position following error detection.

Thanks,

Bill

General Mach Discussion / wierd behavior

« on: April 11, 2008, 11:51:49 PM »

Hi,

I was running a program when the machine started a x axis move before reaching the correct y axis point.  I checked the program which is correct.  There were also no missed steps.  I don't know what caused this.  Is there anything that could make mach not complete a line before moving to the next?  I have turned off the screen saver.  Should I also turn off the 'auto off' function for the monitor? 

Any ideas would be appreciated.

Thanks,

Bill

General Mach Discussion / M5, M3 and Estop issues

« on: April 01, 2008, 03:17:58 PM »

Hi,

This Shizouka I am retrofitting has a built in motor control panel consisting of a number of relays.  It is designed to take momentary M3, M4, and M5 commands.  So when mach outputs a steady signal for M3 and M4, and no signal for M5, it causes some issues.  My first step in dealing with this was to use a normally open, normally closed relay between the mach signal and the motor control panel.  This works for controlling the motor, but screws up the estop circuit (built into the motor control panel) which is a normally closed circuit.  I purchased some interval relays to change the signals going from the relay to the motor control panel to momentary and am going to try that.  Is there a way to change the way mach sends out M3 and M5 commands to momentary signals on separate pins?

Thanks,

Bill
