General Mach Discussion / Advice on acceleration and velocity settings for servos

« on: September 11, 2014, 08:28:21 AM »

Hi All

I wanted to refine my servo tuning in Mach3. Sometimes I get servo errors. I have not found
any helpful information with internet searches regarding acceleration and velocity settings for
servos. My servos are dc brush 850 oz in motors from Dan Mauch at camtronics. The z and y
axes are geared down with timing pulleys in a 3 to 1.  I must admit I never got around to setting
up a reduction on the x axis. I just installed and have working the Ethernet smooth stepper. I`m
hoping this addition to the machine will improve the servo performance. The encoders are US Digital
250 line.

My current acceleration and velocity setting in Mach3
X axis accel:   24.0--vel: 125
Y axis accel:   20.0--vel: 100
Z axis accel:   8.95--vel: 84

SmoothStepper USB / Ethernet smooth stepper problems

« on: September 07, 2014, 07:05:06 AM »

Hi

I have a 5 vDC supplying the board. I assume I have the + and - DC voltage correct. At this time I do Not see any LED so I`m not certain the board has power. I did the network adapter configuration but since I`m getting no feed back I have no idea what is wrong. I setup mach3 with the plugin. During Mach3 setup I get this error: The wakeup client board does not rely. Also, even after setting up the network adapter the connection shows a red X. No idea where to start the troubleshooting process.

Regards Barry

General Mach Discussion / servo hot to the touch

« on: September 01, 2014, 04:51:38 PM »

Hi Group
Today I was doing some 3d cutting.I was only 30 minutes into the cutting and my Y axis servo motor was too hot to the touch. The z andy axis are doing the most work in the cutting I`m doing. I checked the other axes and the z and x arenot even warm. Any ideas how to troubleshoot this problem. It seems when I restarted I had lost my position. I ran the Y axis by turning the ball screw and it does not seem like the axis is binding.
I was running the machine at 1800 mm per minute. I have in the past, run the cnc at 1800mm perminute without problems.

General Mach Discussion / Fusion 360 and Mach 3 post error

« on: August 01, 2014, 11:41:01 PM »

Hi
I just generated my first code in Fusion 360. When I attempt to run the code I get this
error : Current point same as end point of arcLine 21. I was changing setting in the general
config section. I changed the Distance Mode and IJ mode hoping that a change would help
my error. Now I have no idea what those setting should be.
Need some help this is a bit over my head.

General Mach Discussion / Parallel Port Tester. (Software)You can use to trouble your parallel port

« on: May 05, 2014, 09:45:05 AM »

Hi

Anytime I change to a different PC my biggest problem is setting up my parallel port. Just found this software
and tried it. Just create a directory in windows / program directory. Make certain the dll is placed in the same
directory as the drivertest.exe. I used windows 7 and it worked great

General Mach Discussion / No machine movement after resetting limits

« on: May 04, 2014, 01:01:16 PM »

Hi

My cnc was working fine. For a long time I was working with no limits enabled. I then decided
to enable the limits. I have no idea what I`ve done. Now it seems the dro show movement.
But the machine will not move. Port 1 shows 8 pins active. I did the driver test and all seems fine.
One thing I was using a photointerruptor  for the z axis limit. The wires fell off and I replaced them. But
now I wonder if the wiring to the limit is wrong. Could a incorrect wire orientation of the limit cause all this trouble.

General Mach Discussion / Shuttle pro assign buttons for single step + and -

« on: April 29, 2013, 10:54:41 AM »

Hi All

Just got a shuttle pro off of ebay. I have the x y z moving with the outer ring. I`m uncertain how to assign
buttons for single steps plus or minus.

Thanks and regards Barry

General Mach Discussion / Possible parallel port problem

« on: April 16, 2013, 03:57:42 PM »

Hi
I`m having a problem with my parallel port. Just yesterday the cnc was working fine. I had to upgrade to
another machine and transfer the parallel card to the new machine. The settings seem OK. But I cannot
jog the machine.

Here is a link to the xml file I use: http://woodsolutions.com/downloads/2008%20Inch.xml

General Mach Discussion / how accurate is your diy cnc machine

Hi
I`m trying to get a feel for what I could expect from a diy cnc regarding accuracy.
