Servo testers are cheap/simple and you can get some pretty big/powerful servos for models... http://www.ebay.co.uk/itm/P4PM-GT-Power-CCPM-Servo-Consistency-Master-Servo-

Hi, I'm run out of axes on my saw machine and would like to have one additional axe without the connection to the PC. Is there a way how to manually drive stepper motor with MPG (incremental encoder).

i looked at that page several times but managed to miss the script language reference. got it now.

Manuals are here: http://www.machsupport.com/help-learning/product-manuals/#tabs-2

the mach3 manual in section 10.9 says "The operator>Macros menu iten displays a dialog which allows you to see the currently installed macros... The dialog also has a help button which will display

Troy: Please don't hijack my thread. :) Start a new one if you have your own questions. However it sounds like you're getting some success with your machine. Nice job. Matt.

25600 steps this is per inch as long as your steppers are connected directly to lead screws.

One inch = 16 turns. One turn = 200 x 8 = 1600 steps. 1600 x 16 = 25600 steps per inch. Sounds like you have it right. What results do you get if you move one inch, G1 X1 F10 from 0,0,0 ? I use about

16x8x200 is correct

Configuration of pulses per unit.?There are s few ideas floating about on how to do this. but let me tell you what I do have.? Motors are coupled directly to the shaft? no reductions. Lead screw

Did you go into device manager and under computer did you change the acpi driver to the standard pc driver. Sounds similar to what I had going on when I first started out. Also go into your BIOS setup

I installed XP, Mach3 ,C11bb,used XP optimizer. Install with main Driver OK, 4 steppers. I've had eratic results getting motors to run, but move smoothly. Time in int. goes from 10 to 17 erraticly.

UPDATE #1 I now have the motor moving. (PERFECT) Now my next issue. I need advice on getting a set of switches that will help square the machine when I home the X axis. To this point I have not used

I am adding a second motor and lead screw to the X axis on table top CNC running Mach3. ( Going from a center drive axis to having a lead screw on each side to avoid any gantry racking when cutting.

i have a part that has a bunch of features (mainly pockets) that i drew separately. each one has 0,0,0 as its center so i can use G52 offsets to control the location of each feature separately. this

i have an old Emco Mill of similar or maybe older vintage. the only interface capability it had was a serial port. here is a pretty good article of the history of the Compact 5 and it describes

Kenny : The last version posted of GSim is version 1.015. If you load roadrunner, and then select GSim.. what messages are listed in your mach4 error history. Do this in wxMach so we know its at basic

Alright thanks chuck and Rex. I'm going to go to the local electronics recycler and see if I can get lucky! Here's hopin. Matt.

Art, I have tried all versions of GSIM on my system, a MachMotion with Galil controller. Mach4 goes into failure immediately upon trying to startup under the diagnostics tab. The screen goes into

Right, too far back for me. :) rex
