General Mach Discussion / Mach3 always hesitates in arcs and circles

« on: September 11, 2017, 07:49:01 PM »

Hi ,


I have something that has been bothering me for months now.

When I am milling splines and circular movements like helix ramping my spindle always moves kind of like in shocks and not in a smooth movement which leaves marks on the finished parts, also it slows the process time. It is like when he mills splines after every line of g3 code the spindle pauses for half a second to continue the next movement. It drives me crazy.

In settings i have read ahead 200 lines on, so why doesn't he know what the next movement is going to be.

(Servo motors, leadshine drivers, )

I really hope someone has an answer to this, or is this an inherent problem with mach3 that a smooth movement in helix ramping without hesitations isn't possible? Cause than I have to look for another system. But I like mach3 so I hope there is a solutions to this.

Thanks in advance all of you

I remember that there is somewhere a complete setup file in the from of an XML file, you have to put that one in the correct folder. After u set up your mach3 there is a way to export all settings in an XML file, in case u would loose all, like you have.

I don't remember all exactly sorry.

Good luck.

General Mach Discussion / Connect 2 toolsetters? 1 fixed and 1 to set workpiece height

« on: August 13, 2017, 05:12:39 PM »

Hello,

Is it possible in mach3 to connect 2 different tool height setters? I want to set one tool height setters fixed on my tablebed and use another tool height setter to find the height of the workpiece.

I would program a macro to calculate the height difference after a tool change so that after a tool change I can just use the fixed tool height setter to zero out the new tool in comparison to the previous tool.

I can find the probe settings in mach3. So the moveable toolsetter is not the problem to connect. It is the fixed on I am looking to connect.

Any help on this? Anybody wrote a macro like this already?

Thanks

General Mach Discussion / Machine servos stop but mach3 keeps running movements as machine is moving.

« on: August 13, 2017, 04:52:38 PM »

Hi,

The title might be a little awkward. This is my problem. Sometimes my machine hangs, meaning the Y motors stop turning but mach3 keeps moving the coordinates, which is kind of a problem cause my zero point is lost and I need to throw away the piece I am making.

Servo motors are closed loop, but sadly enough it seems that Mach3 is completely unaware when the motors stop . So my question is , is there a solution for this.

Secondly, does mach4 take feedback of the motor positions?

Thirdly, are there controllers that are able to keep track of servo motor/driver positions (linuxcnc or edingcnc?)

Thx for any help.

Regards,

Stephane

SmoothStepper USB / Warp9 smoothstepper or XHC smoothstepper

« on: January 21, 2017, 09:47:40 AM »

Hi everyone,


I was wondering if someone had experience with these boards? Which one is performing better? Is the ESS plugin the extra that makes it better than xhc motion controllers?

I am looking into a new board and smoother motion of my machine at higher fees rates.

Thx,

Stephane

G-Code, CAD, and CAM discussions / Re: what cad/cam for 4 axis machine (3 axis and Rotary attachment)

Hi,

Ok but they have a postpro for mach3?

G-Code, CAD, and CAM discussions / what cad/cam for 4 axis machine (3 axis and Rotary attachment)

« on: September 12, 2016, 08:13:13 PM »

Hello mach3 users,

I have a question. For several months now i have been working with mach3 and solidcam but i am having an issue now.

I want to start using my Rotary attachment but i have no clue what cad/cam software would allow me to import stl from solidworks so i can make my gcode for turn-milling table legs?

Who is willing to put me on my way, i would be most grateful.

Thanks,

Stephane

General Mach Discussion / Re: Determing THe X and Y direction of the workpiece so it can be in any direction

« on: November 10, 2015, 09:47:16 PM »

I think i understand what u mean, although I don't see the point yet. Load gcode and press start that is basically all i need the screen for. Oh and auto tool zero but besides... I don't know.

OK, thx,

So this means I will have to buy a probe and connect that somewhere on the mach3 board. And than learn how to work with this in mach3.

Any idea which screensets for a 6 axis machine have these functions build in and are really good?

Yes yes, this is what I mean.

Maybe I explained stupid. Both axis are indeed remaining always in a 90 degree angle. That's unchangeable.

The question how do I set the y axis to be in angle. Cause I don't know under which angle my workpiece is under. I want to kind of probe the edge of the workpiece so mach3 knows under which y axis it has to work.

If that is done under a g68 code I have to put it in the code, which I don't want as my code is generated in the postpro perfectly. Mach3 should know that there is an angle and work than the code. You understand what I mean?
