Yes, the laser just seems to be a cylinder with a shank fitted into the collet. Obvious really. Undoubtedly there would be a box of magic to go with it. If it could do a clean cut through 2mm...

Following discussion with Frank, if you want to do this from within a sbp file, deleting the value doesn't work, but you can feed it a large minus value - it doesn't go down on doing an estop!

If I am browsing for information to get me going on something where I know nothing, if there is an FAQ I usually start there. So how about the top line on the forum being a well organised, SB managed...

From Frank:
The way we do it on the 5 axis machine is to set the safe to no value. Delete whatever number is currently there.
I can put this into my Autocad toolpathing script as an option, with a...

Thanks Brady, I will try that.

Hi,
There are several things I do with shopbot for which it would be disastrous if I hit the emergency stop, space or S. Using a slitter saw, cutting a moulding that went under the part etc. Is...

Thanks Brady,
I will definitely contact SB first when/if I go down this route.
Allbest,
Ralph.

Hi,
I have a PRT (modified benchtop) with a 4g board with 5 driver slots all occupied - 2 on X, 2 on Y and a Z. I want to add another Z spindle, so need another driver. The software seems to have...

Brady, I don't think it has to cost an arm and a leg. I just cut a square hole in a standard er25 plate spanner and use a standard cheap automotive square drive torque wrench (I hold them together...

Could try:
1. zero using with a bit in the chuck you know zeroes well.
2. put the bit high up in the chuck and return to z=0.
3. loosen the bit and allow it to drop onto the work.

I have done...

Hi, Have you looked at just mpounting the spindle a couple of inches higher on the z plate?

I have a Busch 1.1kw oil filled pump (out of a cake factory) for pucks and it works like a dream. It only starts to smell if the vacuum gets much below 20 in HG - ie the cfm goes up.

Hi, is there any way of changing the font in the command screen, or making it bold? I have just changed up to 3.6.46 on win7, and it is plenty big enough but almost too thin to be readable - it was...

Ps: at the project the operator is almost obsessive about cleanliness...

Hi,
No I change collets quite often - and my usage at my own shop is very low - I would say at least every 2 months of low production level usage. The collets are the large ones, not the mini...

Has anyone with a spindle tried bearing collet locknuts on their ER25 spindle? I have recently gone over to using a torque wrench and am somewhat amazed at how rarely cutters fell out when I was just...

Hi, We have done cutting shapes to 140mm deep. I had some 170mm x 16mm spirals made for it, which worked OK, but found that there was a lot of burning above the flute (and sharpening made it...

If you are doing deep heavy cuts in hardwood etc, then I think that in order to minimize vibration, the heavier the structural build the better, and this is in part based on the size of the collet...

I realized that the torque wrench doesn't have to be anything special as the torque stresses are equal and opposite however far the nut is away from the measuring point (I had thought that the...

Hi,
Current most workable is 13mm depth, 2mm x/y cut from an open side (the pockets are dovetail sockets and pins), about 4200mm/min (this machine uses mach3), about 14krpm with 2 flute. Anything...

Hi,
We are by default using UP (5 micron) collets that cost £32 (at least $50) here in UK. What I have relaxed a bit on is throwing away both bit and collet following a slippage (a very expensive...

Hi,

I am trying to cut pockets and profiles about 140mm (5.5") deep in solid African Bubinga, using a 3Kw spindle So far the best results we have had have been done using 170mm 16mm up-spirals...

How deep are you cutting?
I use 16mm (5/8) x 170 cutters 2flute to cut 130mm deep (Bubinga - it JUST about works...), 14mm insert straight incrementing in from outside up to 60mm deep (works a...

Hi from UK.
1. Check pinions for wear, if over 1 year old on heavy use, change anyway.
2. If the error is consistent along an axis, and all mechanical and software issues have been eliminated, you...

Jack,
If the curve is fairly gentle 1 way (ie you are not trying to lay it on a ball) you can make it up as 2d, slice off 1.5mm, and vac-bag glue it onto the shape, preferably in the same wood.
