DeskCNC quality???

I had the rapid traverse wound out to over 1000 IMP, but it skipped steps occasionally, so reduced it to 650. I haven't squeeezed the machining times too much, because once the program starts, I go back in the house until its finished. Does your Z axis move freely when system is off? Mechanical binding may cause the fault. I have worked on an 11 axis system with two Z's which were air cylinder assisted to reduce upward load. My current Z set up will usually drop the router when power is removed, as the "ball screw" and plastic nut are not the ideal units for this application.

Looks like you have a stepper system vs a servo, which should be faster. All the axis are very free.
Have you ever tried V Carve Pro, where you use a V shaped bit that is constantly in motion on all 3 axis at the same time? Like I said, pocket or contour not a problem all day at the settings above, maybe faster... but I don't see the need to hammer the machine around on short moves.
Carving is a real test of the machine, and I would like to know how others are doing with a similar set up?

Correct, 500 oz in steppers, two on the Y gantry. Yes, love the V Carve Pro. I use this for most of what I run, as it is so easy to use. I've done a couple of sign jobs which had me looking like a wizard. It's an excellent value, and it generated DeskCNC G-code with the included post the first time out. It's great to design, test and preview the end result before firing up the router in a comfortable environment. I've been thinking about their new Aspire, looks pretty good.

I did purchase VCarve Pro, great software. Still working with slower speeds on carving that I would like, but I don't like to push the envelope anyway. Looking for ways to make a little cash with the machine now....BG

So how are you figuring your Ipm carving speed? Is it the sum of all the axis speeds? Just wondering.

For each tool chosen for a given toolpath generated in VCarve Pro, you can set the feed speed (X and Y), as well as the plunge speed, (Z). If you generate a carving toolpath at one setting, you can generate the easier profile cut out at another. The generated toolpaths can then be combined when saved through the post processor, which is an awesome feature. Currently it can only be done on my DeskCNC setup if the same tool is used. I'm working on a way to simulate toolchanges from V bit to flat end mill bit, so I don't have to change bits and rehome the Z.
