It hot end worked fine the first 500 hours and then stopped heating to the set point temperature. Nothing changed. Maybe the heating resistors need to be replaced.

MAX v2 stock hotend stopped reaching its setpoint temperature (225) over night
From one day to the other my printer's hotend won't reach its setpoint temperature anymore. The setpoint is set to 225, it heats up, but it is very, very slowly approaching only 215. And it seems like that with each subsequent attempt the maximum reachable temperature will be lower. I recycled the printer power and tried again, but this time it was only slowly creeping up to 207. The heatbed heats just fine. I don't think it is a problem with the power supply. I read on the SeeMeCNC forum that a PID re-tune might help, but I expect that the heating resistors might be at the end of their lifetime. Any other ideas?

RE: Running a Rostock Max with Marlin Firmware
And I guess that a delta machine is always noisier than a Cartesian printer because it runs all 3 motors all the time. I think the firmware has some kind of an impact. I remember that the Prusa MK2 has different run modes in the firmware settings that impact the noise level. Running the motors in the low power mode makes the printer very quiet. I wonder, if that can be done on a Rostock, possibly by using Marlin instead of Repetier.

Glass plate option
It would be cool to ship the Pulse bed with a glass plate instead of the sticky sheet as an option. I print with ABS and like it when the print just pops off the glass once the plate cools down. Additionally you'd get super smooth surfaces printing on glass and the glass doesn't wear off.

RE: Running a Rostock Max with Marlin Firmware
I was just thinking that a Prusa MK2 runs with marlin and a Rambo Mini and the motors are super quiet. Maybe with using marlin on the Rostock Max 2 the motors might be configured to run super quiet too.

Running a Rostock Max with Marlin Firmware
I was wondering, if there is anybody who is using Marlin firmware successfully on a Rostock Max V2

RE: Filament not sticking to bed
I you might also want to try to enable the Raft setting for your print. That will put a few thick layers of filament on the bed first and print your actual model on top of it.

RE: ABS prints lift off, while PLA sticks too well, using Buildtak surface.
I get pretty good ABS sticking results with 80 C bed temperature and Elmer's glue stick primed glass surface.

RE: Stuttering and leaving blobs during printing.
Look at the MatterControl terminal output to see, if MatterControl is sending a continues stream of commands to the printer, or pauses in between batches of commands.
I had an issue once where MatterControl was pausing in between commands because it was dealing with errors writing to its database. The pauses went away after the database issue was resolved.
