Dan, thank you.
At this point, I am mostly concentrating on organizing the logistics of the
kits, packaging, negotiating pricing and incorporating all the improvements
I was able to make to the design with all the help I got on this site.
But I will definitely let you know when I get some rotating ball nuts available.
So keep in mind I've never used UCCNC, but I have a question anyway. Doesn't UCCNC run in mm, or does it have a option some where to set it to inches? Maybe that's what is making it not run at the correct speed for the G0 moves? But it wouldn't make sense that the cutting feed rate would be correct. Maybe read up on the manual or one of the guys will double check your settings? Is there a menu where you set it to mm or inches? Maybe post more of your set up screens and a report for the guys who know about UCCNC to double check your settings?
And thanks for letting me know about the ballnutz I'm thinking pretty hard about converting over since I'm not a fan of the rack and pinion drive that is on my machine. I would just need to get some gear boxes for my motors so I can keep the gear ratio I have currently.
Dan
Yes, my bad. Software runs in units and you set up the units to inch or metric.
Olf, then how come that the machine runs slow to the cut but runs the 360 ipm when cutting?
Can you post the actual g-code? And you UCCNC .pro file
That's the only way to know for sure. From the info that you've posted so far, it should be able to.
Are you actually running the code that had a feedarte of 850ipm?

Below is the code I ran for the video. It seems it has the F850.4.
I am not a windows user so please bear with me. I looked
and searched for UCCNC.pro and could not see it and don't
know where to find it.

The first thing you should do is figure out why you think you are cutting at 360ipm, and V Carve or Aspire is telling your machine to cut at 850ipm.
The Profile file is called yourprofilename.pro, in the UCCNC\Profiles folder.

Can you upload the actual vectric file? I'd be curious to look at it and see what you had the feed rate set to and check the tool paths to see what's going on. I'm also guessing that what's happening with the 850.4 feed rate is your machine is just running at the maximum feed. I would have thought you would have gotten a error prior to running it, but broken record over here I'm using a different controller and don't know if uccnc will let you exceed the maximum feed rate limit or if it gives error messages if there's a problem with the code.
Either way post the vectric file and I will look at it if you want. I can fix it if the tool feed rate is wrong and repost it for the you.

If his axis velocities are indeed set to 400, if the g-code tells it to go 850, each axes will move at a max of 400ipm. So he should be seeing all moves at his max speed of 400ipm per axis.
Seems like several different things are going on.

Here are the individual toolpaths for 1D 120ipm; 1D 240ipm; 1D 360ipm.
There seems to always be a F-code which is faster than the given Vectric feed rate.
Here is the profile:
Each toolpath for the individual cuts has the tool feed rate set at 360 ipm.
And you can clearly see in the video that each cutting speed is different.

The g-code files don't tell us anything, except that you are doing something wrong in V Carve.
You need to save the file with the toolpaths and post that.

That profile has all of your axis set to Velocity = 2000.
It appears to have all the default values. And it's not the profile you are using when you are posting screenshots.

Gerry, please elaborate.
These are the toolpaths generated by Aspire. What other file with the toolpaths do you mean?

Do you think it's the PP he's using that is causing the G0 not to work?
How do the units work in uccnc/mach? On my controller it asks for inches or mm when you do the initial setup once set all the values are either inches or mm, how does uccnc and mach know what type of units you are using if there isn't a setting for the type of units that you are using?
It seems confusing if the native units are mm and you are using inches for your parts and machine travel. Does that mean you have to use a calculator if you are using the imperial system and multiply the velocity by 25.4 to get the speed in inches?
If so wouldn't 400 be in mm and actually be 15.7ipm? Or is that where the steps come into play?
I also don't understand the homing speed if that's 100imp that seems pretty crazy fast to me.. Maybe I'm just not really understanding how uccnc works and it's confusing me.
I think I'm going to download the manual before I keep asking dumb questions.
