It can be argued of course that doing small pieces on the LR4 (42" x 72" capacity) doesn’t make too much sense. However there is a ton that can be learned in preparation for doing a large piece. For example, if the piece is going to take 12 hours, you are going to need to pause at some point, almo…

Very cool and thanks for explaining. I have been wanting to attempt a 2.5 d project. Just not quite there yet, pause seems a bit nerve racking maybe running like say some cuts then have it go home and then start back from home again?

very nice! are you using both x and y endstops? That way you would just need to be cautious with Z on new startup.

[image] Travis : pause seems a bit nerve racking maybe running like say some cuts then have it go home and then start back from home again? Yes, this can work, and, I’ve used it successfully. There are some advantages since, as you say, you can start each carving step from the same home po…

[image] Riley: are you using both x and y endstops? That way you would just need to be cautious with Z on new startup Yes, I do use both endstops, but that’s not the problem. First, the endstops only save you if you are using separate runs for each tool. This can work fine of course. But t…

so I recently had a project saved by endstops. I cannot remember what caused it, but I HAD to restart my machine. Since I used the endstops as my start point, they were guaranteed, that way I only had to worry about z. for me Z was easy, but for you it may not be. You may need to set up a way th…

Since I used the endstops as my start point, they were guaranteed, that way I only had to worry about z. I guess that could work if you are using the x and y endstops as the (0,0) position and you can simply bring the gantry back there manually, assuming no offsets for squaring was needed. Then…

O.k. so what i did was move to a known spot. Say 50 x 50 y and set my corner zero there. When my machine stopped i was able to re home move to 50, 50 and zero xy and z probe. Very repeatable. It was nice as my mpcnc did not have endstops. So, if you write down your x y coordinates before you ze…

What controller setup are you using?

What controller setup are you using? The board is the simple SKR 1.3 running Marlin. The stepper drivers are the 2209s and there are dual endstops on Y and Z, of course. It’s basically the firmware supplied by V1 although I purchased the board separately and had to modify the FW slightly and up…

[image] Riley: So, if you write down your x y coordinates before you zero, you to can start stop. I think that this is the rub. As far as I know, I have no way to know those coordinates exactly; I also don’t know what gcode line the machine is on, so if the machine is turned off, I have no …
