−
−	~~=== Temperature ===~~
−	* The [[HotBed]] can be heated to any temperature up to 70°C by default, and up to 110°C if reconfigured.
−	* The [[MK-1]] can be heated to 260°C (limited life); we recommend sustained use at 250°C or below. PLA, PET, ABS and Nylon work well at 225-230°C
−	* The [[EMO-25]] prints at room temperature
−	* The [[VOL-25]] can be heated to 100°C
−
−	~~For more details about each head, see the page for that head.~~
−
−	~~=== Resolution ===~~
−	~~Engine SR positional resolution is better than five microns in the X and Y (0.005mm), and better than half a micron in the Z (0.0005mm).~~
−
−	~~Engine HR positional resolution is better than half a micron in all axes (0.0005mm).~~
−
−	~~=== Accuracy ===~~
−	~~Engine SR positional accuracy is +/- 50 microns in the X and Y over an 8” travel area, and +/- 20 microns in the Z over an 8” travel area.~~
−
−	~~Engine HR positional accuracy is +/- 20 microns in all axes over an 8” travel area.~~
−
−	~~=== Repeatability ===~~
−	~~Engine SR positional repeatability is about 25 microns in the X and Y (0.025mm), and about 10 microns in the Z (0.01mm).~~
−
−	~~Engine HR positional repeatability is about 10 microns in all axes (0.01mm).~~
−
−	~~=== Layer Height ===~~
−	~~We have successfully printed in ABS with a 25µm (.025mm) layer height, but this is very time consuming.~~
−	* We often use a 300µm (.3mm) layer height with the .5mm nozzle on the MK-1 for 1.75mm filaments.
−	* We often use a 600 µm (.6mm) layer height with the 1mm nozzle on the EMO-25 for pasty extrudables.
−
−	~~=== Print Speed===~~
−	The best print speed manageable (without sacrificing quality) is variable, and depends not only on the material being used and layer height, but also on how much mass is being moved in the X and Y. We normally print at 1.5m/min, or 25mm/sec with both the MK-1 and the EMO-25
−
−	~~=== Build Volume ===~~
−	~~Engines have a build volume of 200 x 200 x 200 mm.~~
−
−	~~=== Form Factor ===~~
−	~~Engines are 13” wide x 15” deep (plus 7” of rear space for spool rods), and are 21” tall plus heads, which can add another 10” to the height.~~
