Check to make sure that the Z-axis isn't binding up somewhere. Also check that the timing belt is 'drum-tight', and free of oil, grease, etc. RayHex

Hi all, Is there a formula to help select the proper voltage and current for a foam cutter ? Any special wire ? Dave

A decent parabola would require a rather large billet to start with, and a lot of material to be removed. I agree that it would be a good test. The proposed test came out of a discussion of

I have posted D2nc version 1.0.1 at www.d2nc.com available for download. Most of the feature requests I received have been implemented: IJ absolute mode. Selectable compensation strategy. User

I've been running a Boss 5 from my pc for over a year now. I use Deskcnc, which seems to do a great job of running the mill, but I don't use it much for programming. I've got gecko 201s and

If you decide to replace the motors then seriously consider fitting servos. It will probably work out slightly more expensive but the reliability and speed will be far better than steppers. Les Tim

Yes, a flat plane and a bowl are excellent tests for a hexapod. You might also include a parabola. The focus point would be a good (if analog) measurement of both the overall shape and the

Dan, You will most likely want to replace the stock drives with something like Gecko G201 units and a matching power supply. The stock drives are known for failing and are very old full step or half

Ah, OK...I understand what you're saying now...Yep, I agree. Mike Graham Stabler wrote:

I came across two Bridgeport BOSS's one made in 1977 the other made in 1982. Both of them are stepper units. Can I operate them using PC running Mach 3? What kind of difficulties might I

WOW! That's fast, I was thinking of using a carbide insert drill from Allied Machine & Engineering Corp. (Doall) Thanks for the information! Charles <skullworks@...>

I'm just saying that the quantization exists, you said it didn't because the number of decimal places in the control program matched that of the steppers. There will always be some difference

I've been dreaming of a CNC conversion of a knee mill for some time now. For the past couple of years, I've been reading all the familiar Yahoo groups (DIY CNC, CAD CAM, Mach, Gecko, etc) along with

If you go the CNC route, I'd strongly suggest you look into one of those 'slugger' type drills. They cut much faster, and with less power than conventional drills, and you don't have to drill through
