Safe Build size for the UM2+ in Simplify3D?

Recommended Posts

I know similar questions have been asked before and i read a bunch of them already, but I am still not quite sure and i'd rather be safe here.

I just found out the hard way that Simplify3Ds Ultimaker2 Profile isn't quite correct for the Ultimaker2+, as with its default bed settings of 230 x 225 my print head crashed straight into the right wall or the rails or something, I was not best pleased about this.

At least I was right next to it and cut the power rather quickly, just to screw up a 2nd time by homing the head without lowering the bed first, so it hit the glass clip on the way home.. Not my day today it seems.

2 Questions if I may:

1) Anybody know of some safe settings for Simplify3D so this wont happen again?

2) Is there some sort of test or things i should check to make sure i didn't damage the printer? To me, it looks ok, the next print was fine, but I am not quite sure what i need to look for..

Thanks for you input

Ok, yeah 223 * 223 sounds reasonable indeed. I don't have the first clue what caused it to slam into the right wall. The object was "scaled to max" in S3D. All i did see is that it was trying to print the first line of the brim when it did hit the wall, there was nothing unusual there i think.

One thing i did notice that could be behind all this maybe?

When Cura sliced objects start to print, the head moves straight forward towards me and it starts priming / depositing this small spiral of filament pretty much right next to the left next to where the front glass clip is located.

If i print a S3D sliced object, the head moves slightly diagonal and deposits this a good 1 cm further to the right pretty much on top of the clip. Offsets maybe? I wish i had more of a clue ;-)

Hmmm.. i guess that would indicate something with the Start code perhaps? But I didn't modify that (except for taking out the first line where it increases the stepper current, i was told that's not good for the UM2+..)

Even if the area is set too large in the slicer, shouldn't the firmware stop with an error instead of crashing into a wall? In tinkerware you can adjust the maximum buildsize directly. I guess that standard firmware has all the same parameters but just missing in the menus. Are those parameters set wrong? Or are they meant for something different?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
