SmoothStepper USB / Smooth Stepper Causing Different Motion in Slaved Axis

« on: January 13, 2010, 06:09:39 PM »

Hello,

Currently operating with Y and C Slaved. Distance is different and gantry twists?  Have had similar issues if non-motherboard mounted parallel port used in the past.  Any suggestions?

Have tried noise and decreasing max frequency in Plug in Control to no avail.

Help apprreciated!

So....

Are there any settings people that need to cut 3D (or V-Bit) files use to get Quantum? 

Is there a happy medium between 3D and 2D optimization?

Brian,

Thanks, the licence worked. 

2D files have improved dramatically.  Corner rounding is just about eliminated with Quantum.  Speeds, and acceleration is way more than twice as fast now. 

Funny thing though...

Now 3D files barely reach 5% of feed.  Any ideas?  With Path Smoothing, does it matter if you are in constant velocity or exact stop?  So far testing reveals no major differences.

Thank you Brian,

Quantum is making a signifigant improvement, and I am pleased to finally learn what No FRO on QUE means! 

What kind of timeframe are we looking at to get a version of Quantum up with no limit to line numbers.  Testing 3d is a bit of a challenge otherwise.

I need to UP this post because everything Scott said goes doulble for me.  We have run test after test with Exact Stop On, Exact Stop Off, CV values all over the map, Look Ahead set low and high,...everything that Mach codes for.  The results are still inaccurate cuttiing.  We have the feed rate override (which really should just be called Override, as it also controls the Rapid move (which is not good  )) set at 100% or less all the time. 

Judging by the lack of response when Scott asked about inlays, I suspect that no-one using a CNC router with Mach has had enough accuracy to achieve this (which some would consider basic) application.  Anyone?

V-Bit carving and 3D also experience the rounding problem.  This is not just a 2D phenomenon. 

I feel bad for Scott, and I don't know if it was clear from his last post that the images posted were not made using Mach. 

Physics lessons aside, is there any light at the end of the tunnel here?, because we are running out of track!

G-Code, CAD, and CAM discussions / G1 on every line causing choppiness

« on: November 03, 2006, 12:49:47 PM »

Hi,

I am experiencing a weird situation where our machine gets choppy if there are G1 codes on every line of a 3D file.  If the codes are removed the machine is much smoother.  Any suggestions on ways to overcome this in Mach?  We use a number of CAD/CAM packages, and some have posts that are not easy to modify.

Does anyone know the code I can put into a couple Macros to Enable and Disable the Soft Limits?

Is there any way we can call another G-code file from within a program by using M98?  I have tried  a bunch of ways but with no success.  I have a few applications where the benefits of batching files would be huge.

In other systems you can simply call a file by entering M98 "C:/My Documents....".  That would be very useful IMHO.
