Version #8 question-Shadow Shading

I am readying through the PDF for the upgrade, and have watched the videos. My question is: is the "Shadow Shading" option just a visual effect, or does it actually modify the model itself?

Re: AXYZ Millennium Slow Spindle speed

Hi Scoones.

Try this input. F2-auto-24000-enter, and run a short test to see if that allows the rpm to rev up.

also try F2-on-24000-enter, and see if it revs up to the desired rpm.

If you have a manual handy, check the settings for your inverter.

Re: Need a compression bit

I like to use single flute mortising compression cutters for thinner materials 3/8" or less. Here at my local supply shop, I get them for $42.00 to $50.00, for the no name house brand(off shore).

Not sure if you are interested in the offshore versions, or the name brand ones?

Re: Drag Bit for cutting vinyl,paper and the like

I have the WidgetWorks Vinyl knife. I've been using it for about 5 years without any issues. It's quite pricey, but it's well made, and has certainly paid for itself many times over. I use it allot for cutting magnetic material as well. It uses a standard knife, that you can buy from the manufacture...

Where did you find the "Regular Grid Importer"?

Please disregard, I found it.

Re: 2 days work down the drain!

I have lost a couple of stepper drivers in the last few years. One started to loose steps, and the other burned. I'd have to side with the lost steps, whether it be an electrical or mechanical issue.

Re: Acrylic UGH! Not Flat.

I use both extruded and cast, and don't have problems with either one. I do use an extra sacrificial MDF waste board if possible. I use the vacuum and two sided tape to hole the extra board in position. Humidity will play havoc with MDF, so if the work is being done over a couple of days, I will res...

Re: Feeds and speeds for very small Router bits

Hi Leo. No offence at all. I think we come from a vary similar background. I spent over 25 years in CNC metal machining, and I've learned that each individual machine has it's own sweet spot. I've seen one cutter work great on a horizontal mill, but be less than productive on a vertical mill. I engr...

Re: Feeds and speeds for very small Router bits

I engrave 304 stainless with a 1/32 solid carbide 4-flute FB stub end at 12000 rpm, 6-ipm and .002 depth of cut. You will have much better tool life if you can ramp into the material. I use a .100" ramp distance. I can get the same endmill (except a ball end) for about $7.00 per cutter. This is a re...

Re: V-Groove bit problem

Hi Allan. Yep, those are the ones. I use the ones from Dimar. I have a 30,91 and 110 degree versions. A few years ago, a friend of mine was in the shop, and he picked up one of the cutters, and was looking at it, and said "hey this is cracked" and sure enough it was. I called up the supplier, and he...

Re: V-Groove bit problem

Hi Allan. I have this problem from time to time when cutting dry cedar. I've learned that you only get one shot at it. I will sometimes put a little offset on the tool path, if I absolutely need to do another V-cut. I have invested in index able carbide "V"cutters. Yes the body is expensive, but the...
