The shield is a drain for noise/stray signals. Connect at controller only (most of the time).

General Mach Discussion / Re: Need help on Dyna 2800 Mill Conversion to Mach 3

   It is a wonderful machine.

   Not knocking here nor trying to offend, but this is more of a software use site. Have you been over to CncZone? Also join the Yahoo group (Dyna Mechtronics), it is not very active but does have some info.I do know there are a few people who have successfully been able to feed them Gcode with little to no modifications. Tbirdgreg over at the zone had a great website that told exactly how to do it but it has been pulled down for some reason (you might try pm'ing him).

   I personally have a 2400 and 3000. Both which run Mach but most of the electronics are long gone and now running Geckos or PMDX stuff. Had I known then what I have learned since, maybe the original stuff would have been fine. I couldnt find anything for a long time info wise.

  Barring any electrical problems already in the machine you would just need a breakout board, most likely you can feed it as is.

Thanks for people like Jeff who spend the time and effort trying to make the blind see.

This has been a fun journey. Being a hobbyist,
means my income is not dependent upon it. In fact it drains most of that. The constant challenges demand thought, reading and research. Then it will all change again.

They are telling you, your settings are limiting you. Not the machine. Or that remains to be seen if your XML was provided.

Hi Fastest1
Its set at 1000 (debounce), but still do not know if there are any bad effects on this number, it was my best guess!!!!
Graham

   The debounce setting is a measurement of time (40 microseconds per unit). A setting of 1000 means the signal has to be present for 1000 x 40us (.0399999 seconds).

   Some noise is very short in duration and it is acceptable to remedy the problem with the debounce. A problem where much higher numbers are needed indicates a wiring problem, generally ground issues.

   I come from a hobby machinist background. .03999 seconds is not long to me and nothing will be damaged if my machine over travels at a rapid speed for that period of time. Now that might not be the case for those with commercial machines that are capable extremely high rapids (700-1200ipm possibly?)

   This also brings up another point. The length of time of this setting will influence where the home or limit switch is seen. It will move farther away from the status change the longer the signal is required. Again these are concerns, but most likely arent serious for hobbyists and our machines. 2 different settings would result in 2 different home and or limit locations, minutely different if that was critical.
  
  Anyway that is how I understand it. Hope it helps.

So is your opinion that noise from the router is killing the operation? Going to be hard to cut your file without the router ;-) You never answered the question about the power settings.

Just depends on the accuracy you need. I would generally think the graduated dial would be sufficient, however tying in an additional limit/home switch is easy enough ( though I procrastinated it for years and still managed to make a few things, like holes in my table and vise, I wish that part wasnt a joke!)

Just out of curiosity, what is your debounce set to?

General Mach Discussion / Re: Setting up a touch plate in mach

« on: September 29, 2013, 12:54:44 PM »

   Are you familiar with Mach and its settings?

   Mach wil allow you to assign the pins for inputs and outputs etc. Many machines are set up to only use 1 pin for all of the limit switches. Since Mach knows which axis is moving and in which direction it thinks the next trigger will be the axis in movement. It will zero that DRO and move to the next axis to be referenced.

   Now the reason I asked and stated the above was to have you verify which pins are being used in the "inputs" section of Mach. You need to find which input pins are available. You will need 1.

   To make and or use a touch plate, the easiest thing is to buy a piece of PC (printed circuit) board. This is available at RS in small pieces which is all you need. Solder a long wire to it. Lay this on your tables surface, conductor side up. Attach wire to input, enable the input. test connection on diagnostics page by manually touching the plate to your tool tip. Does the light on the diagnostics page indicate the circuits status has changed (does the light for that input light up upon touching the board to the tool?). Btw doing the manual test prior to use allows you to confirm you and your machines safety. Still guard the E Stop ;-)

   You will have to go in and set the thickness of the touch plate in the "offsets" page. This will 0 the axis upon touching accommodating for the PC boards thickness (if you entered the correct thickness).

   I hope that helps. If not ask more.
