Both, in the preview the toolpaths don't go all the way to the bottom of the material and when we cut it it's stopping 1/4" short of the bottom. We cut through 1" and thicker material all the time...

I am trying to cut a 2" OD x 1" H hemisphere out of 1" Corian. No matter what I do I cannot get it to cut the full 1" depth and it has been cutting my 2" OD to 2 1/2" OD. This enroute software is...
Guys, I really want to do the Shark and Eagle one, but when I open the DXF files up to cut with our laser cutter there are a ton of errors. Either errant lines or missing sections, like gaps in the...
Might have missed it, but are you looking to do rectangular ones or the round ones?
If round, I would suggest a lathe...and there is even an inexpensive option that might do the trick for you. I...
I'm looking for a paid apprenticeship in the Honolulu area on Oahu (although I will drive within reason). I would love to find a smaller machine shop, maybe doing custom work or marine work, that...
Good to know. There is a local Service Center that handles a large number of high-end and low-end foreign cars in this area right around the corner - I always see 4-5 Porsches and the odd Rolls in...
This is the way to do it. The Avery Paint Mask is a self-adhesive film that you can cut/engrave right through, then paint/enamel your part - peel the film away when the paint is dry - and you have...
Sorry all, wasn't trying to confuse (hence why I didn't put the picture inline).
Just trying to show that the idea of two lower cross-braces on a gantry IS a great way to go - and is very rigid....
How much power do you want? Would 36VDC @ 10A work out ok for you?
That's what I did with mine and it is seriously rigid (well, except for the unsupported rails).
Yeah, that is one thing that concerned me. Although, the Jewler said that the ring could be shattered with a hard blow from a hammer?
Wow, 35 years - that is awesome.
Thanks! No, it came...
Yup, that's right - big day is September 20th! :banana:
Cool part (well, one of many) is that my ring is Tungsten/Carbide! Shouldn't have to worry about damaging this bad boy!

Hey Mike - Where do you get those little parallel extension cable dealies? The ones that you have going from the board to the back of the enclosure.
So, the Y-Axis Servo Mount had to be re-designed. Turned out I made the standoffs too tall and there was too much side-to-side mis-alignment between the pulleys.
So, just turned the standoffs on...
Interesting thought FPV - will look forward to seeing how they work out for you.
I've had my belts and pulleys for a few days now and put them on the finished machine. Once I button up the...
This big glaring mistake...er rather, just something I didn't think of:

With the servo mounted this way for the Y-Axis, the Z-Axis servo...
Of course, I need to mount the Servo to the front plate for the X-Axis!
Here you can see where the spindle for the X-Axis ballscrew come through the front frame-plate:

Making the Z-Axis Ballscrew bearing-plate. For ease, I decided to make it out of polycarbonate. I will make a new one out of aluminium down the road...
Forstner Bit, Poly-carb and the top OEM...
Ok, bolted the Y-Axis Ballscrew to the Crossplate.
Now to make the Z-Axis!
Here is how the Ballscrew and Linear Slide will be laid out (more or less) for the Z-Axis:
...
Well, my belts and pulleys will be in tomorrow! So excited, just hope they are all correct.
They are all 1/4", so that means I have to bore one of them out to 3/8" for the Z-Axis ballscrew - but...
Well, with everyone's help - I think I have worked it out. At least, I hope so - as I am ready to place my order with SDP/SI.
Holy crap are they expensive though! Looking at $105 for all the...
Ah ha! So it does, and it makes a big difference!

I downloaded and ran the Kollmorgen software and plugged in what I could from my CNC Machine's specs. I filled in what I could and got this:
...
Oh man, I was pretty excited about this when reading through the specs/description - until I saw it is only for Linux. Bah! Hate, hate, hate (did I mention, hate?) Linux.
Ah well, sounds like it...
Why wouldn't I want to run my Servos at their rated rpm (2150rpm)?
Ok, I'm not sure if 200ipm is even neccesary on the Z-Axis (I know it was just an example). Also, if cutting the gearing in...
Ok, tons of good info there to digest, thanks guys.
I am using Gecko G320 drivers, and the encoders are US Digital 250 CPR units.
Using Mach3 on a P4 1.6Ghz machine.
Ok, so GT2 belts it is.
Going with the 3mm GT system (largest in the list, no GT2 listed) - I get this:

I changed the Belt Grooves...
Ok, for example:
Assuming 2:1, for my Y-Axis - which has a 4" center-to-center - this is what I get:
