thoughts and opinions wanted regarding homing and restarts

[awe-source]

Hi there! (to anyone reading this... obvi...)

Just wondering on whether you use/want/find problems wiht the zhoming on this...

eg:
big model that takes up a lot of the base plate, might BE where the head does its homeing on your printer... and thats gonna suck!
eg2:
but at the same time, there doesn't seem to be a lot of consistency around "how YOUR particular machine knows where it is in z space

so we're thinking that while the "skip homing" is good SOME of the time there are a few things that the system doesnt know...

so:
do we add a "my z height IS 34.3mm just trust me" for the restart dialog?
do we add some kind of config that says (hey, when a print fails or I cancel or <insert any number of events, including I pulled the power on this...!!!> then my zheight will be ... so a lot of completion scripts have a +5-10mm z just to move the hot end away... but pause doesn't do this... and you don't always catch the failure ON THE LAYER you want to restart at...

so anyway, looking for thoughts and suggestions for what might work for YOU.

I'm actually using your plugin for the first time. My print takes up almost the entire print area. The failure I experienced was that the printer stopped extruding but why i don't know. As the printer kept "printing" but no filament was being extruded I know know the height where it stopped. Using calipers I know the print is 7.2 mm high. As I can only home x and y but not Z i manually had to set the hotend to the height I needed, home x & y, and start the print.

I attempted to use your plugin but it raised to 7.2mm and started printing. This was of course too high. I edited the Gcode and restarted.

It would be great if your plugin had an option to start at a height or a manual position. I.e. at 7.2mm in height but not raise the hotend just start at that layer and continue from that point.

This is actually a very interesting idea... and may have synergy with superbobs request to start/stop...

We'll investigate how this might work... maybe add/change the disable z homing to be custom... or something like that... "allow code to dictate start height or override with zero (I've set the z height already) or whatever... maybe even allow something like negatives (it's 10mm higher than it needs to be to clear an object but I want to start printing after a -10 move...

Could be complex...

But a good thought nonetheless

Another suggestion is to enhance the documents for the plugin. While I am technical, retired IT, I have a couple of friends who are into 3d printing who are not. I have suggested to them to install your plugin and one of them after looking at it flatly stated they didn’t have a clue how to use it. While I get it is very hard to write documentation for everyone I have to agree it is not clear what is needed for the untechnical folk. Great idea for a plugin and this is something I think the community needs.
