Just a comment-- using Mach3  and the program addons from newfangledsolutions.com, what is the best way to generate G-code for machining. We have found that the G-code from BoB CadCam still needs to be written with additional G-code to correctly run.

General Mach Discussion / Debugging printer to controller communications
« on: December 03, 2006, 10:25:13 PM »
We are trying to debug what appears to be a problem between the computor 25 pin parallel port and the controller 25db input.
We are running a 3GHz Celeron with 150g hard drive, 1Gb ram, MAch2 with a xlyotex controller on a small shark cnc.
The machine runs and stops intermittently, We have checked ALL switches and connections and are quite sure the problom is either the computor parallel port or the controller. the questions are: !. does the setup in Mach2 when setting the ports and pins screen change the pins from the setup that drives a parallel printer? We can look at the signals when the printer is run with an interface monitor and see the signals as the printer prints ok. 2. Does the reasignment of the ports and pins  in mach2 change the pinouts from the setup for the printer? Assuming (dangerous to do) that the parallel port sends signals to the controller, we should be able to monitor the drive signals to the controller as the router is running. There are some signals that are fed through ( limit and home signals) that are NOT involved. Without a pinout of the controller inputs and verificationof the data being sent to the controller it is difficult to determine if the computor parallel port is not working or the controller is not. When the programm is run it runs very erratic and jumps out of sequence. We have been throught the checking of the switches and are confident the problem is in the data transfer. Help!!!

Has any one had the opportunity to look at the data stream from the computor parallel (db25) port that goes to the controller? I have used a breakout tester (EIA INTERFACE MONITOR) that is used to view with leds the data as it is transmitted in both directions for data terminals and other DTE/DCE fed equipment.  It appears when I look at the data transfer on another computor that it is connected online with a parallel printer the data stream is consistant and the printer prints OK. ( separate computors)   When the machine computor is conected inline with the contolle,r the brearkout tester indictes the data stream is intermittant, including pin 15 which is the estop conection, could this indicate that the parallel port on this computor is not sending data correctly?.... ANy comment well appreciated & TNX.....

also known as a centering scope. See page 1394 of MSN current catalog, they have one listed. check www.mscdirect.com or call 800-645-7270.
the other possible source is edmund scientific www.edmund scientific.com....good luck, woudn't part with one once you get your hands on one..

Check out Edmund Suuply, they are an Optical supply house with about anything in optics, Might go on google and check optical tooling, I have one (not for sale and is geart for setups on milling.

We are running from a desktop latest thinghere, debounce looks like a good check. am looking at the switch inputs with scope and voltmeter. it looks like noise, the switch lines are on a pullup resistor to the limit/home switches, it is 10k from the power suppply/controller voltage. we had removed all the connections from the switches but left the wires running along the machine, they obviously can be picking up noise from the steppers, the big issue is when did the stopping start and what was the setup when it happened, the programmer made the changes while running the machine, I am the machine oversight but not the person running the machine. We also are trying to pin down if the controller is causing the problem as it is still under warranty. PS.. This project is to let this company see what cnc controlled pattern machining is all about. We are considering the next step with purchase of a Thermwood 5x5x12" machine, will lose the Mach2 at that time. cheers & thanks

We have gone thru the switches all removed from action, vibration. wires contacts etc. It is strange that the Reset button on the screen picks up on stopping the program, unless somewhere in the settings something is wrong. The stopping is random during run but occurs from startup to 1/2 min to after stopping it occurs about 30/50 seconds of running.  We are trying to determine if the controller could be at fault or the computer is causing the problem.  the computer is a Celeron 3Ghz, 1 GB ram, running XP. Mach2, from BobCad/Bobcam. technicrdd

We are having a problem with programs stopping during a run. Thr steppers just stop and the RESET button (on the Mach2 screen) starts flashing
and the program and the router stops. On the screen we can click on the RESET button and click on CYCLE START and the program runs from that point. After 30/50 seconds the same thing repeats. This occurs on other programs likewise. We have checked the cables and voltages and are normal per the trouble shooting guide. This acts just as we stopped the machine by clicking the RESET button or PAUSE and then continued on clicking the flashing RESET button and clicking on the CYCLE START. We can monitor the pins, etc with a scope or line signal test but do not know what to look for. Any comment or suggestions will be greatly appreciated..TNX Technicrdd & TNX--We are running Mach2 with G-code from BobCad/BobCam, 3 mhz processor, windows XP. controller is xylotex 3 axis,

I need help--I am not familiar with the use or how to do a screen shot can you give me the directions?    We are trying to recoed the setup screens for a setup to Mach3, I assume that a screenshot would allow us to get hard copies of the setups...TNX
