Is there a way to clean the perf boards without scaping them?

eg: bathing or paint and wipe

how much time do you have ?

would you consider alternative base plate ?

Most people don't bother trying to remove the old plastic that gets melted into the perfboard holes. There really is no need to unless you are wanting to print raftless I suppose.

I can get the model of the perfboards, but the raft is hell to get off :oops:

mb20music is right. It makes no difference to remove the plastic in the perfboard holes.
But you need to scrap the surface after each print.

I must be different from everyone else. I clean every hole after using a perfboard. I take a permanent marker and mark the bottom (doesnt matter which side just pick one) of the perf board. So I always know which side to push the little plastic bits from. (I usually do that with the tip of the tweezers) but I don't have to clean it too often. I've found that with a clean board, if I just let the print cool down the plastic shrinks enough that I can just flex the board a little and the print and raft both come away fairly easily, rarely leaving little bits in the perfboard

Would a acetone bath solve my issue of removing the rafting from the perfboards?

Really? :D

I know the more holes are free, the better the new print adheres to the plate, but I don't bother cleaning them out. When I have a big ABS print and need slurry to keep it well-bonded, almost all the holes are free after taking the print off.

If I really wanted them free I'd probably let the board soak in acetone for a night... that's as far as I would go...

I think that would work, with ABS, but never tried it that way... For HIPS this could be solved with limonene.

But are you maybe printing too hot? Do you also have problems to remove the workpiece from the raft? Otherwise, dropping the temperature 10° would probably help too.

The board I use I made it myself. It is 4mm thick and has 2mm holes in a offset pattern. I used that one board for almost one year now. Each and every print is 100% okay. Using raft is a must with this board. For cleaning I use the painters knife which came with my UP mini. Also I swithed back to UP original filament. No need for temp control with original filament and the print comes out as expected. The board can take some abuse from knifes and sanding paper. Because the holes are 2mm I can hit the tabel a vew times and the loose pieces come out. I can also let them be and print over it. It simply does not matter with this board.
No need for glue, tape or slurry.

Cheers

Yes... OEM filament is the best but I'm too cheap to use it... :D

You shouldn't need to go to such extreme measures to clean the boards. A scrape is all they need and the the old dots in there held the new print weld to that footing. Keeps the dust off them and they should require little work. If you have problem with getting the raft to stick print a little lower. You really want to smoosh that first layer into the board to get good adhesion.

There is also a shiny/smoother side and and dull/rougher side to the perfboards. Don't use the shiny side as it has lower adhesion.

Those with Plus 2s you don't have to settle for the autoset height. Often we find it is too high and you need to adjust it lower after you autocalibrate.

Once you use acteone you will often find you need to keep using acetone so if you avoid that route then you can have nice low maintenance boards.

I have been using my 3 boards for 2 years and have only used acetone on one. It now isn't as relaible as the others and I save it for PLA.
