Solved Max Print Speed?

I know the settings in matter control say that it can't get over 60mm/s but when using Cura or even Simplify3d? would it be unwise to attempt to print say at maybe 100-150mm/s?

 

I've seen people print at 100mm/s on a stock robo. I wouldn't suggest it unless you're looking to experiment. Generally higher speeds leads to more print issues.

If your printer doesn't have them yet then I suggest printing these rod caps to secure the rods a bit more onto the top lid:

I think mine stock already has something in there that looks similar? Should I reprint and use this one instead?

 

Yeah if it's a simple print that doesn't really have any detail you can go 100. I would not suggest going any faster than that without modifications. Greg's wade is heavy on the carriage. That is a huge limiting factor.

 

just out of curiosity. What modifications would be required for a higher print speed? I hear that machines like the ultimaker can print at like 150

 

Going bowden is one of the main things. Removing the weight from the extruder. The faster you print the more cooling for parts you are going to need too.

 

If you are curious as to what 100mm/s looks like, here is mine with the Volcano hotend and a 0.6mm nozzle on it:

That extruder stepper was quite warm after this (needed a prototype in a hurry) and my next adventure is to add active cooling to the steppers.

 

Yeah, I have a pack of those cheap stick-on fins for the stepper drivers (bought a 100 pack from the slow-boat, have a bunch left) so I figured I could use those, then print a clip for a 40mm fan too

 

That's nice!
Yeah, I figured I would need to extend the X axis limit switch screw and shrink my build area, but I am already planning to build a giant Robo using the existing files from Robo and Mike Kelly, I am going to use Mike's carriage so I can play with dual extrusion (and I hope he adds a dual direct drive option so I can do flexible in dual) I am also enlarging every axis, so that would give me the option to add cooling to each and engineer the clearance.
