Mach4 General Discussion / Mach4 build 3390 - Keyboard Inputs
« on: May 27, 2017, 01:47:47 AM »
On build 3390 the Keyboard Inputs seem to be messed up. On the Inc (XplusINC and etc.)  ones I can't make them work without a hotkey, they always control the X axis. This is on the demo version. Anyone else have this problem.

The Feed Hold does work when I press the Space bar. Using it as an example I tried to make the Esc key do the stop function but it errors out on me. Below is the code...
Any suggestions will be greatly appreciated.

--this works for the Feed Hold
if mc.mcSignalGetState (mc.mcSignalGetHandle (inst, mc.ISIG_INPUT63) == 1 then
     mc.mcCntlFeedHold (inst)
else
     --  Do something else
End

_________________________________________________________________

--This errors out
if mc.mcSignalGetState (mc.mcSignalGetHandle (inst, mc.ISIG_INPUT623) == 1 then
     mc.mcCntlcycleStop (inst)
else
     --  Do something else
End

General Mach Discussion / Z axis count loss after running 3d profile
« on: July 02, 2009, 11:12:12 AM »
I have a small router table. The 3 axis all check out fine when you put a dial indicator and run a test back and forth. But when I run a 3D file that has a lot of Z up and down movement, it seems to loose some counts. The file takes about 8 minutes to cut and the Z axis will usually be .003 to .005 inches lower than when I started. So I have to rezero the Z after every run. All motors are the same and the velocity set to 150 ipm, the acceleration to 6 and the step pulse to 2. For the Z, I have tried different velocities, down to 50 ipm and different accelerations but they don't affect the lost .003 inches after every run. Any suggestions on what to try to improve this will be greatly appreciated.

Note.. all motors are steppers with gecko drives

General Mach Discussion / Toolpath Display
« on: May 20, 2009, 04:14:55 PM »
My tool path display shows the tool path but does not show the movement as the code is run like it use to. Any ideas on what to look for.
Thanks

General Mach Discussion / Stop machine on bit to jig contact
« on: February 11, 2009, 05:36:25 PM »
I have a jig that is made out of aluminum. The jig is clamped to the wood table and holds the wood workpiece. I want to stop Mach3 if the bit should ever touch the metal jig. That way if something goes hay wire my jig will and bit will be saved. I imagine I can connect/wire the jig and router to some port on Mach3 and issue some command to stop it if they touch and make a circuit, but I really don't have an idea where to start. Any detailed ideas would be greatly appreciated.

General Mach Discussion / Hot Key Codes
« on: January 23, 2009, 02:38:31 PM »
Most of the buttons have a keyboard "hot key" assigned to them but some aren't labeled. How do I know what the hot key is if it isn't labeled?

We know the following since they are labeled...
Cycle Start is Alt + R = 2130
Stop is Alt + S = 2131

BUT buttons like "Load G Code" don't tell me what the hot key is...
All I know is that it is assigned the number 2114. So where can I find the hot key list of what the numbers correspond to.

Thanks
Dave

General Mach Discussion / LOST on setting up a servo motor in Mach 3
« on: January 17, 2009, 12:14:05 AM »
Got my first servo motor in for testing and really don't understand the setup for it in Mach 3 ( my steppers work fine ). I can get the servo to turn real slow in one direction but it will not move in the opposite direction (mach screen is showing moverment). In the motor tuning section I have no idea where to set the "Steps Per" "Velocity" "Acceleration" "Step Pulse" and "Dir Pulse".

Would appreciate some pointers in getting me going the right direction.
Thanks
Dave

Here is the specs on things.

I am using a Gecko G320 with a Cand CNC EZservo board, UBOB and related electronics. The G320 is set as follows.
DAMP and GAIN at the 10 'clock position (8 'oclock = fully CCW, 4 'oclock = fully CW). LIMIT fully CW.

Here are the specs on the motor.
-Skewed Rotor Design
-constant torque: 1.2 N.m ( 170 oz-in)
-peak torque: 6.0 N.m (850 oz-in)
-max. speed at voltage constant: 4200 rpm
-terminal voltage: 72 VDC
-continuous current: 8.8A
-peak current: 40 A
-torque constant (KT): 0.14 Nm/am
-voltage constant(KE): 15 V/100rpm
-resistance: 0.52 ohm
-inductance: 1.8 mh
-inertia: 3.39 kg/cm^2

The Encoder as follows.
US Digital: E5S-500-250-EG-PKG2
Shaft-Mount Optical Encoder with latching connector, 500 CPR

Here is the specs on the ball screw.
RM2505 - 25mm diameter, 5 lead, turn circuits 2.5*2

General Mach Discussion / LPT port Address
« on: December 24, 2008, 04:11:53 PM »
I have a new computer that did not have an LPT port, so I added a card. When I run the GetPortAddress.exe it reports an address of &HDCA8.
In Mach3 what do I put in the Port #1, Port Address box?
Thanks,
Dave

I have some NC files that I need to combine into one file and add a PAUSE and RESUME between them so the first file runs and pauses while I reposition the work and then resume and run the combined second file. I have no knowledge of how to do this in my ongoing education of CNC. Any help greatly appreciated.
Dave

Here is a condensed version of each file.

General Mach Discussion / Probe Digitize Question
« on: May 12, 2008, 03:17:15 PM »
I plan on using the 3D Scanning probe from my compucarve/carvewright with Mach3. Once I have done the scan and have the *.txt file, what software do I need to use to get this into a *.nc file?
Right now I need the cheapest way to convert the txt to nc - demo programs would be great. Once I determine that it will do what I need, I will be willing to sink a few dollars into the software.
