General Mach Discussion / Re: BB card vs motion control card

« on: October 16, 2016, 08:26:59 AM »

If i'm wrong someone will correct me but I'm fairly certain the the parallel port will not handle the encoder signal and pulse rates needed for servos very well. My encoders are 10,000 per rev and motors can do 3000 rpm so it needs a pretty fast connection.

This may be entering into the twilight zone but note to self…
“Tweakie be prepared to be hammered” 

Mach3 is not a closed loop system so does not get to see the higher speed encoder signals that are required by the servo drives to verify that the step direction signals have been performed correctly.

In the end one  can add a parallel card(s) to any computer .

There are many good reasons for using an external motion controller although my personal preference is using the parallel port with Windows XP but
please keep in mind that the parallel port can only be used with 32 bit operating systems running Windows 7 (or earlier) and laptops are not supported.

General Mach Discussion / Re: Mach3 incorrectly interpreting gcode

« on: October 14, 2016, 10:33:35 AM »

I think you need to go into Config. / General Config. and change the IJ Mode.

If you then Regen. Toolpath the display will be correct and the code should run just fine.

Ideally your Gcode should contain the G90.1 or G91.1 (as appropriate) and this is perhaps a failing of your CamBam post processor.

Pics and code would be useful.

But I could do with a radio button to the main screen to turn on Flood cooling and turn it off again the same as M08 and then M09 in a program.

Is there a way of doing this?

Hi Adrian,

Welcome to the forum.

Setup the Flood Mist Control in Config. / Ports & Pins / Spindle Setup. This will let you toggle the Output# you choose for the Flood Ctrl-F (M8/M9) button on the main screen.

It’s a learning experience but using one of the Screen Editor’s will enable more buttons, for example; Mist (M7), to be added to your screen.

General Mach Discussion / Re: Outputs

« on: October 11, 2016, 08:01:06 AM »

Hi guys, I am new here in this forum. But I'm beginning to feel completely stupid. I configured ports, inputs, outputs and everything as described in various manuals and videos. The problem is that the prgrammed outputs, either by M3, 4 and 5 as well as the ones set by macros are working fine (blinking when activated) on the diagnostic screen while I'm running my G-code. but on no pin on the breakout board is anything happening! What the hell is wrong with it. It's a brans new board, so I doubt that anything is wron with it. THe board is connected via USP port. All inputs when activated by home switches for example are fine. The LED's are switching on and the inputs are visible on the display screen. Any ideas??? Please Help!!! Thanks Karl

I think your best plan would be to contact the manufacturer of your USB board to find out which pin is allocated (or recommended) for the spindle control (M3,4,5). Then make sure that pin (or pins) is / are correctly set-up within your plug-in's software.

General Mach Discussion / Re: Can not increase motor velocity (65mm/min). Why?

« on: October 10, 2016, 07:18:23 AM »

I think all the information you need to know about stepper motors and their drivers is contained in the Gecko documentation here; http://www.geckodrive.com/support.html

(Basically, Torque is a function of motor Current and Speed is a function of motor Voltage. 5 volts is unlikely to produce a reasonable speed performance).

Try reducing your Acceleration in motor tuning and see if that enables more motor speed before the stall. Also reduce your Kernel speed to 25kHz (35kHz is not helping you).

« on: October 10, 2016, 02:01:48 AM »

if you are not using an "external motion controller" then laptops are not supported so that could be the problem.
Alternately, have you transferred your Mach3 license file to the laptop computer ? if not then your Gcode could be ending at the 500 line limit of the Demo version.
