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.
So having separate temps for the first layer doesn't make any difference in prints? I was just curious about using it because others I know use Simplify3d and it allows them to select different temps for different layers. Most use a higher temp for the firs t3 layers then drop it down and start the fan. I assumed there was a good reason for it.
Yes. MatterControl and most 3D printing software expects dimensions to be given in millimeters. If you made your design using some other unit of measurement then you will need to scale your model appropriately. You can do this in MatterControl using the Scale menu in Edit mode. It has a built in list of factors for scaling between common units.
It is caused by the fact that MatterControl does not send a single move command but instead breaks up the move into smaller segments. This allows us to do some things that other software can't (like print leveling and babystepping), but one of the side effects is that stutter when jogging. We're thinking about adding a way to disable the move segmentation in the next version.
If you can't connect with either MatterControl or Cura, then the problem is most likely with the board. We've seen this occasionally with Robo printers; contact their tech support for a replacement board.
White PLA tends to require a little more heat than other colors due to the pigment used in the manufacture of the filament. While 185-205C can work for other PLA filaments, 215 is acceptable. If printing at 215 and you still experience clogs, bump up to 220 and give that a try.
If you continue to have issues with this filament please email firstname.lastname@example.org and we'll be happy to assist.
MatterControl only has EEPROM mapping for printers running Marlin or Repetier firmware. Your printer is probably running a firmware which MatterControl does not recognize. You can still change the settings you need to, but you will have to do it by hand through the G-Code terminal. See the RepRap wiki on using the M503 and M500 commands.
