I had my first bearing hit a piece of slag and explode during a rapid
Oof.I had my first bearing hit a piece of slag and explode during a rapid
So glad I went with linear rails for my next table
At the same time.... I had a buddy have the same thing happen with this linear rails.
Is your brother still liking the shop sabre? I finally have dad convinced he needs something to supplement the massive old optical trace oxy rig he has in the fab shop side of the business, but I've only built from scratch or retrofitted electronics. It wouldn't be a production unit running 10 hours a day (well maybe once they step out of the stone age and realize how useful it is), but I want something fairly simple that can be run by anyone after some training. I already have to babysit my 70yo uncle and his 4x4 burntables pos that I retro'd with candcnc brains and really don't want to go down that road again.
It’s a nice machine. Not a fan of the water table, and the control is different than my Mach setup, thc seems kinda slow. Other than that the thing is super smooth and quick. It makes good parts. For the money it’s a decent deal.
That was my next question, I've been using sheetcam/mach for close to 10 years too. Stuck in my ways I guess. The only other table I've used was a pre-lincoln torchmate, and I wasn't a big fan of the interface, but I've been using autocad for at least 20 years so the archaic cad part just pissed me off.
The thing that will get you mad is the pendent is not as good as the Mach stuff. The Mach control makes the pendent smooth and accurate. The shop Sabre it’s basically stepping each click. It’s slow and hard to be accurate.
Have you messed around with that at all in mach? As long as I go back to the very start of the last complete operation in the code (coordinate move, touchoff, pierce) 95% of the time I can start over there instead of the dry run. It took me awhile to figure it out, but as long as I didn't lose step it normally works just fine. My gantry is all aluminum direct drive with a mag breakaway so losing step is pretty rare unless it's from interference from something like forgetting to uncoil the ground lead from the table
Yeah I do that but Mach still needs to run the code to get the move to here before the cut starts. On short programs nbd. On the big ones it takes forever. Almost faster to open the code with the notepad and delete a few 1000 lines then restart.Have you messed around with that at all in mach?

You should be able to pick the start point, no need to run the code from the beginning. As long as it's a coordinate I can select that line and it'll move there and start. I think click the code to highlight the whole thing, pick the line and hit "set next line", run twice and its back on its way.
Interesting... is it because its just a pain to load and unload or just that you've never really had a project to validate it? I daydream about the projects that I have where a cantilever CNC would save me a bunch of time.
Just never had a use for it. I make tons of shit and never needed it. My table has over 6” of clearance under the gantry so all the box tube c channel grouser pads ect fit on the table.
I've seen a few of OG TM users ditch most of the hardware and then build a new, larger table from scratch, so long as it matched the output limits of their original machine. I would do that with mine but I don't even have an AVHC controller so my little blinky box isn't quite up to snuff. Depending on what controller you have, would it be cost effective to have an upgraded hardware setup? My old TM G-code controller software would allow me to set all kinds of motor signal controls as its somewhat of a basic and universal software.
I've got both the blinky box and the newer accumove 2. The blue box avhc died and i couldn't get a new one so the table got the accumove upgrade. Its a better system and height control works pretty good.
I just use a 3D cad program and sheetcam. I can blast out most drawings and programs in a few minutes .
