Stacking LACK IKEA Table Enclosures..  

RE: Stacking LACK IKEA Table Enclosures..

Apologies - I should add that the printers are all Prusa Mini+

Happy New Year to all⭐️

RE: Stacking LACK IKEA Table Enclosures..

It's more important to add concrete slabs between printer and the base it stands on ( in that case it would be a Lack table).

Just try it?

RE: Stacking LACK IKEA Table Enclosures..

Hi, if you have firmware at least in 5.1.x, but probably better to have the latest one, you can download BonkersBenchy_PLA_MINI_IS_16m.gcode , from prusa github account, and print on your printer, for best experience top left one will be the best 🙂 [and try two  printers at once too] so you will see the mechanical limits, and maximum accelerations those printers can achieve, and how wobby the ikea lack table is. And then probably you will want to add something to make the tables more sturdy. But it can work that way anyway 😉 Also you will find that the surface of the table is great speaker, so if you are concerned about noise you can add rubber mat which cut the noise a lot. And in your configuration looks like that if you will want to print Z layer up to 180mm the top ptfe tube and cables will scratch the table, and probably it can even degrade printing tall objects... Still, for small models it's not probably the issue. Good stable tables has supports, most of the time parallel lines under the base plate, but triangles are very good, maybe less practical for daily used tables, but for device support should be fine, when you add them, you can limit linear acceleration a lot, in my test based on the model from 2-10 times, and with additional mat it made the printers much more bearable to listen to 😉

Hi all, Happy New Year and sorry for the late reply

Thanks for the advice, I've bought some concrete slabs, cut them to size and painted them (my local retailer advised this to seal the dust). Just finished setting up the rig so planning to give it a test run soon.

Wow thanks for the advice! That's super helpful - please could you let me know where I can find the BonkersBenchy files? I did have a look on this page on GitHub but I'm not too familiar with it. I'm only asking because one of my printers is set up with PETG while the other two print PLA

RE: Stacking LACK IKEA Table Enclosures..

hi, in my presious message you have a link, just click it 😉 it's for PLA

RE: Stacking LACK IKEA Table Enclosures..

there is no SwoleBenchy for PETG, only PLA, but you could get the .gcode and edit it with text editor and bump bed temperature to 85C and hotend temperature to 240C (something like 4 lines in total) and you should be good to go (probably 😀 )

Ah thank you for clarifying 😀 !

Just before I break anything, the relevant part of the gcode for the PLA benchy looks like this:

M104 S170 ; set extruder temp for bed leveling
M140 S60 ; set bed temp
M109 R170 ; wait for bed leveling temp
M190 S60 ; wait for bed temp
M569 S1 X Y ; set stealthchop for X Y
M204 T1250 ; set travel acceleration
G28 ; home all without mesh bed level
G29 ; mesh bed leveling 
M104 S220 ; set extruder temp
G92 E0
G1 Y-2 X179 F2400
G1 Z3 F720
M109 S220 ; wait for extruder temp

Presumably I just need to make these changes:

M140 S85 ; set bed temp
M190 S85 ; wait for bed temp
M104 S240 ; set extruder temp
M109 S240 ; wait for extruder temp

RE: Stacking LACK IKEA Table Enclosures..

Yes

/ Me runs away

RE: Stacking LACK IKEA Table Enclosures..

maybe to be on the safe side just run the provided gcode on PLA ready printer? at least you will understand what this bonxersbenchy is 😉  still it's printer acceleration and vibrations of the table, PETG is different than PLA

RE: Stacking LACK IKEA Table Enclosures..

ah, and i realized that probably we are talking about two different flies, i don't know the 'SwoleBenchy' but the file i'm reffering to is 'BonkersBenchy' and was released together with 5.1.0-alpha1 firmware for MINI, and you have to use IS to print it:

RE:

hm sorry for confusion,  I meant BonkersBenchy in my posts, not SwoleBenchy...
