Config: {
Power: 12v,
X-Rapid: 283mm/s = 17000mm/m = 669"/m,
Y-Rapid: 283mm/s = 17000mm/m = 669"/m,
Z-Rapid: 43mm/s = 2600mm/m = 102"/m,
X-Size: 1200mm,
Y-Size: 600mm,
Current: default,
Steppers: V1E,
Leadscrew: V1E // 4 start
}

Not even close to performance of Ryan’s LR3 speed test video. My LR3 is wider, so will never match, still, am wondering whether any build/firmware edits would help?

Didn’t test/measure accuracy, or measure driver temps. Just wanted to speed test before changing to 24V power supply.

Wirelessly controlled via ESP3D on V1E ESP3D/ESP01s. Created a “Drag Race” macro.

Speed testing to non destructive failure helped identify things to tweak, e.g. vac hose should be strain relief supported, and leadscrews/emt benefit from lube.
