I tried to use a laptop; but the one LED that was lighting up before didn't even light up for that. I had it powered on; but not logged in. I should try again though. At first, I was thinking that...

Just an update for folks that might be interested...

Shopbot support got back to me that night. They suggested that I go ahead and try the upgrade to 3.8.38. So, I followed the procedure and it...

Hi folks, looking for ideas for the quick fix... Here is the text of my ticket to the shopbot support:

I start the shopbot control software and it could not connect. I have cut with this...

If you cut above your material (Air Cut), does it seem that the pattern is correct but just in the wrong place or does it seem that the size changed as well?

I am thinking that, perhaps, you have...

I opened the flexible channel and found the shrink tubing covering the connector for the stepper. As I had it still on as I gently lifted the segment that had the shrink tubing, I heard the stepper...

OK, sorry for the grammar mixup

I inspected the wiring starting from the Z-axis servo and found that the wires were very tight between the servo and the first cable-tie. I am sure that was my...

Test results....

I did my best to drive the head up and stop it with my hand, it seemed to have sufficient upward strength. I was reaching arms length to press and hold; but it was enough to...

I think it is on the fourth pass from left to right (just before I stopped the cut). On the previous passes you will see that I ramp it up towards the end of the run. On the last left to right pass,...

While I checked this before (from the bottom), when I re-checked the spring from the top, I found that it is rubbing up against the parts which travel along the rails.

Thanks, lots to try.

Is there a test toolpath file that can push the various machines to their limits as a check? I am looking at trying to create such a toolpath file like the one that I did to...

So check me on these modifications please.

For the z-axis feed rate, I could change the:

MS,2.0,2.0

into

MS,2.0,1.8 (or less, I would be OK with 1.0 for now)

In general, I would agree. This started out as a test cut of a part of the pattern which had steep (sheer) drop-offs.

In this particular case, it skipped while it was not even over the test...

Here is the toolpath file up to (and slightly past) the point that it skips.

I dabbled over the last few weeks to no real effect. However, today when I went to check it out, I managed to get the problem occurring on video. Towards the end of the video, you can even hear the...

I agree about terms and I apologize if I butchered them.



These definitions are why I thought machine allowance was the adjustment as to how closely to follow the model's shape and that pass...

I agree that, in the future, I should use a closer machine allowance in the rough cut.

I probably didn't make it clear in my earlier post. In this test re-cut, the skip happened in the area that...

So, I had left the desktop and all on, with the bit in and decided to redo the cut as a test.

1) I zero'd the Z to the spoiler board.
2) I moved it to Z 0.
3) I measured from the spoiler board...

I have had my machine for a while. I bought it with the intent to eventually make a minor business out of its use. So far, I have made some money; but really nothing that I could call a profit on any...

25576I think that there are some contributing factors and I have a way forward for some testing....

1) The pattern had a steep drop-off -- as in vertical.

2) In the more severe case, the bit...

It just happens in 3D finishing cuts.... I don't KNOW that it is a stepper slip in a plunge, it could be bit slippage upon the upward move.
In the upgrade, I did not find any worn parts. Nothing...

I don't recall ever having this problem in 2D... ever.

I doubt the collet has any issue. I have never hit metal in operation and while there is alway dust on it when I pull it to do my bit...

I am having a problem that is new to me -- my Z-axis stepper is sometimes skipping during a cut. It has happen three times now -- twice in the last cut. The first two skips (or what appeared to be a...

I just finished most of my upgrade yesterday. I still have yet to hook up the z-limit switch wire to the controller.

I have the router version and found that, once together, my alignment was way...

I am working the guitar for someone else who is doing the actual building of it. So far, LOTS of learning has taken place.

I do have the extended Z kit for the DT; but didn't want to put it on...
