minor firmware issues

hello together !
just noticed some issues, related to the 3.0.9 firmware that came with my kit:

(1) when a print is started (like the V2Calibration.gcode) and i tune the nozzle temperature to the required value for the actual filament, it first seems to be ok in the main menue.
but as soon as all the measure points for the leveling are visited by the inductive probe, the temperature is then reset to the value inside the gcode-file. so the firmware ignores the tuning value, even so it has been manually set.

(2) i thoroughly aligned the pinda probe height to be +1.00mm on top of the nozzle. but when i navigate the hotend to the 9 probe points using the manual axis settings, i noticed a deviation of more than 0.50mm. As stated here somewhere, the manual axis movement doesn't take the results from the meshbed leveling in account. so far so good but wouldn't it be nice to know the correction values ? or even navigate to the x/y points in exact height (so that the axis movement is based on the meshbed leveling results).

(3) furthermore i guess that the manual mesh bed leveling (where you can try to adjust +/- 50um at the left, right, front or rear) is obsolete and could be disabled when the xyz alignment has been successfully completed.

just 3 minor points (maybe features ?), which could be solved more convenient in one of the next releases...

cheers

<edit>
and another point:
(4) when you try to pause or stop a print, it would be a good idea to navigate the hotend to a safe place ! otherwise the hot nozzle melts the actual halted print.

#4 not minor 😉

This feature is still of benefit to people who need to counter act an uneven MK42 headed bed. You would think the Mesh Bed Leveling would handle it, but perhaps it is limited in the amount of error it can correct. I haven't used it personally, but have seen "before" and "after" photos from people who have used this successfully.

I wouldn't want this. When I tune my temps I save it as a filament profile in Slic3r. I often whack the temps up manually to get things cooking while I am slicing/prepping but it's /always/ the temp in the gcode that I actually want to print in.

what do you think about another feature ?

(4) start printing with a timer

many people know such a feature from their washing machine or their oven.
would be nice if i can start to print from sd-card after a specified time, so someone could set up everything in the evening (prepare filament, clean nozzle and bed, select gcode to print) and start printing in the morning... so the printer might be ready when he/she comes home from work ;).

... or find a heap of ashes instead of his house. 😉

Never let the printer work unattended. Better safe than sorry.

Interesting idea. I, personally, won't start a print without being there so I can watch the first layer or two. Have you looked into OctoPrint? Many of these ideas are best done from a tool like that.

hi John,
thanks for mentioning octoprint. because i'm new in this stuff i didn't knew about it.
but i've already setup a webcam (to watch my prusa printing while sitting in the office) and had several ideas on my own.
:ugeek:
