Is there a way you can swap the axis drivers, cables, steppers for comparison to each other?
Adam,
I’m not sure what you mean about swapping.
Do you mean disconnect the boards in the controller box?
I’ll tell you what, I do remember a while back, I had a problem and I jiggled the big protective tube the cables are in and it worked. So now you got me thinking I may have a frayed cable.
That’s good direction.
Thanks

Component?
Different program

So I’m not sure what your saying.

Yes, a tool or a few other things like a driver or a stepper are all components of the machine.
You swap them with another to trouble shoot an issue.

Here’s a problem.
28’ radius into a 22” diameter circle.
How deep will that make the dish?
You have 10 seconds.
Start ..... now

trou·ble·shoot
[?tr?b?l?SHo?ot]
VERB
troubleshooting*(present participle)
solve serious problems for a company or other organization.
trace and correct faults in a mechanical or electronic system.
So first thing I’m going to do is retire the motors.
Years ago I had a motor that didn’t work, then I giggled the long protective shield on the wires and bam! It worked.
I bet that’s it.
After that I’ll try changing drivers.
And so on and so forth.
Thanks for your help.

Re: Vetric Aspire nose dive on Z Axis
[QUOTE=peteeng;2302786]2.25 inches[/QUO]
.1801 is the correct answer.
28’ radius in a 22” wide dish what us the depth or height.
This was directed a a contributor with an amazing snarky attitude.
He said to me... “and you’re going to teach”?
Eh wm....?

wm.... is a very valuable contributor to this forum.
The fact that you know the answer to a question you asked yourself does not necessarily mean much.
Re: Vetric Aspire nose dive on Z Axis
When I was teaching I knew what I was doing. I taught my students troubleshooting and how to swap out parts if needed to solve a problem. They now have jobs in the real world, some of them are darn good, better than the teacher!

The oddity is he insults me for being a teacher?
The beauty is ... I’m trying to teach boys in jail an honest option to dealing heroin.
This will be the way.
I just purchased Vetric Aspire.1995
“. “. “. 2 MACH 3......... 350
Various parts for my build totaling $4700
I’m pretty committed to my calling.
I don’t need tounge in cheek, snide remarks.
Just help.
Isn’t that what this site is for?

One of the most frustrating things in attempting to help someone is when the person asking for help doesn't follow the help they are given. After seeing an op repeatedly ignore advice, it becomes difficult to keep the snark out of the responses.
How do you know what was followed

And having successfully taught for a number of years (12) and starting a computer lab for my own students I had to use hand me down computers that came from the CAD lab with Zero software. I installed legal copies of AutoCAD LT on all 20. You will soon find your one legal copy of Aspire and one computer is not going to work for 10 students.
PS There is a much greater need for machinists and welders than someone who can run a CNC router. They could be taught to weld in a few weeks of classes.

The Vetric Aspire license at $1995.00 includes 40 seats.
I’m sure you don’t know anything about my program.
The boys are court ordered. It is a 24/7 facility with sentences in the range of 6-18 months.
Reading and math levels for these high school age boys are around 3-4th grade. Most if not all have traumatic related injuries, both mental and some physical (or abuse). Most are on meds for ADD and other physiological issues
So, in order to “hook” them, we need quick positive reinforcement.
Welding is one of those programs I teach that gives them the quick hit.
But, the CNC work, designing a simple box or rubber band power car, is exactly that! A quick hit.
Most of these boys sell or do drugs or both!
So the issues we have to juggle are sometimes overwhelming.
I give any other “shop teacher” a week with these boys and they’ll crumble.
It’s not easy, but out of 140 we may get 5 to go on to college or trade school.
Hope the insight helps your understanding of another world many will never venture into.
