General Mach Discussion / Re: G-Code and Dwell Button

« on: March 20, 2016, 07:52:29 PM »

I did set the IJ mode to Absolute and Inc (same for the Distance mode) but the result is the same. I’m looking now in my CAD/CAM program to see if there is a setting for the IJ mode

Thanks Hood

General Mach Discussion / G-Code and Dwell Button

« on: March 20, 2016, 05:05:57 PM »

When I try to test run my gcode in Mach3, the dwell button blinks, the status line shows MIN-Z-.0625 and the program stops. After a few seconds the status line says “radius to end of arc differs from radius start, Block=N100……” and the CV Mode button is green

My cam software runs the code to the end with no problems

I attach a part of the gcode

What is wrong in my gcode?

General Mach Discussion / Can’t Backout from Limits

« on: March 12, 2016, 02:55:45 AM »

I have set in the Settings screen the AutoLimit OverRide but when I jog any axis and hit a limit, the machines stops, the status line says limits switch triggered but then I can’t jog out (I get the windows which says to fix it, I click fix it and still can’t backout)

When I trigger any limit by hand, it works like it should and in the diagnostic screen I have no lit LED. Estop and Probe works

All limits are set to Active Low (Green) and if I set them to Active High (Red) triggering any by hand non works.

Where should I look to fix the problem?

I dont know about the PC you mention but for my last cnc I bought a used Dell Optiplex, Intel duo core, 17" LCD keyboard and mouse for $53cdn + tax. There are a few stores here in Montreal selling used PC's and in the past and now I'm very happy with the selection they have. My experience with PC's for Mach3 is the oldest the better and I never connect them to the Internet. I always use Dell and never had a problem. If you are close to Montreal, visit Encan Depot, 1170 rue Begin, Ville St Laurent, H4R 1X1, 514-331-5353, www.encandepot.com

Thank you bfgstew for pointing out to me

Re wiring all as per post #14 now the probe works. Using my script the bit went down to touch the plate and up 1” as it should. The LED light in the diagnostic screen is OFF and the volts between the plate and chuck is 5.1 with correct polarity (black wire to clip and red to plate)

However I must point out that this wiring is not a universal fix for the C10 BOB. To my limited knowledge in electronics it depends I think on your router spindle insulation. I have used the C10 before with other routers like the same as I have now (Bosch Colt), air cooled spindle and a Taig spindle and never had any problem neither did use any resistor. When I used the air cooled spindle I also had the C41 variable speed control board.

Thank you all for the help

Now that I removed the DB9 connectors and my black / red wires are connected straight thru from panel to clip / touch plate I thought it’s time to give a new try.

Went back to the original Mach3 setup (put pull-up/down jumper back to pins 1 and 2, re connect the Estop and all limits) and using the same wiring setup as per my 1st post (black to 5V with a 120 Ohms resistor, red to pin 15) I get the following

Active Low setting (Green)
LED light on Diagnostic screen is ON
When I touch the clip to the Chuck LED remains ON but when I touch the plate to the bit LED goes out
Volts = 5.12 but with the red meter tip to clip and the black meter tip to the plate. Otherwise I get a negative reading

Active High setting (Red)
LED light on Diagnostic screen is OFF
Volts = 5.12 but reversed as above (red meter tip to clip and black meter tip to the plate)

Nothing else was done because I don’t understand the meaning of the above

I’m sorry stirling for all the time you wasted but as I mentioned, in my mind the wiring was good as per my continuity test when I installed the black / red wires

I know they are PITA but when I installed them I checked continuity from the panel to clip / plate + from the two DB9 shells and all was good. Now I learned my lesson and will never use again

I don’t know what happened but to test my DB9 connectors I shut down the PC and power to the control panel to avoid any short-circuit. When I restored power the red wire was still on pin 15 and black wire on GND. The LED was OFF in the diagnostic screen and touching the clip to the plate went ON

Did that 3 times and then the LED went ON and stayed ON. So I decided to remove the DB9 connectors and solder to wires to have a direct connection between the panel and clip / plate.

Touching the clip now to the plate a dozen times the LED always comes ON and stays OFF when the clip is not touching the plate.

The DB9 connectors are ok. Black wire from the panel is connected to the clip and red to the touch plate
