General Mach Discussion / strange behaviour / offset

« on: September 16, 2012, 01:56:47 PM »

I have a JCUT CNC with the USB interface.

from time to time, I get the machine not going to the requested coordinates input in g code. for example if I do z50, it may go z51. this happens very little but in the middle of long machining this is a big pb (see pics).

mach 3 shows the right coordinates. If I pause the machine and start again then if catches back the right coordinates.

any idea?

Mach SDK plugin questions and answers. / probe scanning XY direction

« on: July 23, 2008, 01:55:09 AM »

hi,

the wizard for 3d scanning is good, however going up and down all the time is slow.

does anybody has developped a wizzard which would work as follows:
- start of scan at z depth.
- when probe detects touch, then it raises Z till end of touch.
- move X or Y step.
- if no touch then move Z down till touch
- then up one setp back and X or Y+

and so on?

to do this the probe shall be able to detect lateral contacts but I beleive it would be much faster way of scanning...

if this exist please let me know where to find the code!

General Mach Discussion / strange steppers behaviour

« on: August 04, 2007, 06:22:21 AM »

hi,


with mach 2 or 3 when I drive the stepper (with or without load), I noticed that whatever the speed is, there is every seconds a small shock or vibration in the stepper like "clack" noize (I counted exactly 60nos per min). It can not be due to stepper as it is not depending on RPM.

without knowing anything, I would say that there is a clock of the computer which is interfering with the process but which...

any clue of what is happening?

my system is core 2 quad 2.4ghz + xylotex 4 axis sytem.

Mach Screens / separate preview screen design

« on: October 23, 2006, 01:50:37 AM »

hi,

does anybody has made the same interface as the original but with the preview screen separated so that it can be displayed on a second monitor?
if so, I'd like to have it!
