We should put better signage on the sheets ASAP.
Enjoys working with metal, welding, blacksmithing, etc.
RE: Prusa I3 MK2
It may have been a chemical reaction between the alcohol and the 100 degree kapton tape. It didn’t just wipe off. There was sanding and scrubbing with water. I’m the one that did it.
I’ve cleaned the bed with alcohol before too. I didn’t notice a reaction at lower temperatures. Unless the bed is greasy let’s just stick with water

Back ups of Makerspace data
Can we do this? I have my own folders backed up, but should everything be done?
Far as I know, there is not really any on-site data, except maybe the financials. All the CNC machine gcodes are essentially ephemeral in nature… We might leave them on drive for convenience of re-running a job, but there is always a master drawing or file to fall back on, and in which the edits happen. I suppose we could back up the slic3r and cura configs, and maybe the firmware settings for the machines, but it is just as easy to post our findings to the forum as we’ve been doing so that if we ever need to rebuild the configs, we can naturally do it on the more recent software.
There are a couple of general “email, checking status on jobs and looking stuff up” machines floating around (one in the craftorium, on in the lounge, one in the hack room… But they really don’t hold any special data.
I’m not sure what all lives on the design lab machines, but I suspect that the software lives on the computers and people keep their files on key-drives or other storage.
If and when we ever get proper network storage set up, it’ll likely be cloud backed in some way.
RE: Potluck 7pm Sunday
After action report: We had good food and good company.
Was sort of sad to see that some people I was hoping to talk to did not make it, but still a good time. Prime rib roast, gurkensalat (which is different from the space’s usual fare of kabel salat!), coleslaw, soda pop, potato salad, two types of pie, lemon truffles, and likely some other stuff I don’t recall.
I’m going to try to BBQ there at least once a month through the summer (I’m also going to try really hard to show up at least once a month…). Expect burgers or bratwurst or something occasionally.
RE: Prusa I3 MK2
After several failed prints I’ve made an adjustment. I’ve very lightly sanded the kapton tape on the print bed with 220 grit sandpaper. This was one of those suggested steps that I was reluctant to take as it cannot be taken back.
I’ve made the live Z adjust at least -0.5mm. Seems to be working fine.
I’ve also adjusted the normal print setting on the octoprint for a wider brim and forced support material. Hard lesson: in slic3r you must save the configuration changes on the print tab before slicing or changing tabs.
Other lessons: Don’t clean a hot print bed with alcohol. It leaves white ghosting. Water and a J-cloth do better. No lint from the paper towels. Still better to clean it at a lower temperature.
