General Mach Discussion / Re: How do you apply a different offset from home on a slaved axis?

We could do that if we made sure Y and C were in the same orientation to each other before turning on the machine, but we would like to avoid having to do that as it adds a manual step to our homing process.

"I think he wants to offset each side different amounts from the home switch."

Yes this is is what I want to do. In my case both axis are rotating the material but they need separate homing sensors and it will be extremely difficult to get each homing sensor in the same location relative to eachother.

At this point we have both axes slaved together, and each are homing to there individual sensors. Now I would like to make their 0 location at different values away from their individual homing sensors. Is this possible?

Trying to slave two axes together (Y and C) but in our case we will need to be able to apply a different offset from home for each. Is this possible in either Mach3 or Mach4?

I wonder how difficult it would be to update to mach 4 with our machine... Is there a lot of people who have done it? 

We've also had kind of a strange problem that when our machine accelerates during a feed-rate its fine, but de-acceleration is kind of clunky. It accelerates to speed well but when it slows down to stop its is not nearly as fluid and can come to an abrupt stop.  Never happens during rapid travel just during cutting or when a feed rate is applied. From what i've been experimenting with I have a feeling its something to do with the increments we are applying in the g-code but i wonder if we would have this issue with mach 4...

General Mach Discussion / Re: G4 Dwell time only reading whole numbers

Tried it couldn't get it to take milliseconds. What we ended up doing is using and inverse feed rate value to tell it to move a certain increment over a certain time, then it was able to take decimals.
For example
G0 Z2
G1 Z2.001 F240

60/240 = .25 seconds, so it would take .25 seconds to move .001 (2-2.001)

General Mach Discussion / How to slave an axis with different steps per

« on: March 13, 2019, 10:48:16 AM »

Trying to slave the C axis to the Y axis. The problem I am running into is the C axis steps per is 2.25 times greater than Y axis steps per. I changed the C steps per in motor tuning but it keeps taking Y steps per since it is slaved to it. Is there any way to slave an axis to another and apply separate steps per values?
Thank you,

General Mach Discussion / G4 Dwell time only reading whole numbers

« on: March 01, 2018, 02:54:46 PM »

Whether I have .1 seconds or .9 seconds as my dwelll my machine is pausing for the same amount of time. This is also true for when I have 1 second or 1.9 seconds for my dwell. It seems to be only reading whole numbers. Also, I tried switching to milliseconds in general config but even with milliseconds selected it is still reading the values for the dwell as seconds. Can anybody help me? Is there some setting I have to change somewhere?
Thank you,
Beau
