Hello, black box uncontrollable movement I'm French sorry for the G. translation. I have a problem with workbee 1500 and the blackbox. The machine no longer follows the grbl routes. My grbl code is good (tested on foam no problem) (makita router at least 1) - Uncontrollable movement - 4 failed attempts on wood with 3mm pocket 3d passes, uncontrollable movement and the cutter plunges several mm -6mm> 9mm (makita router half power 4). - EMI - I have grounded the makita router. I kept all low voltage wires as far apart as possible. I grounded the chassis. Questions : -I must earth the shielded wires of the 4 motors? -I don't know if the grbl code changes due to the EMI? -I must earth each cart? -Change my earth wire with an armored one? I cannot find a solution for the uncontrollable movements. Thank you
The straight line runaways do look like EMI: see docs:blackbox:faq-emi [OpenBuilds Documentation] But do rule out as well: - acceleration and max rate not too high? Could cause stalling during rapid moves. In particular if you do not have OpenBuilds motors. - mechanical: shaft coupler setscrews tight, etc
sorry for the translation Hello, the displacement is 1400m / min - 500m / min in diving - pass of 3mm. nema23 motor, mechanical drive, I will ground everything. - If I change the speed while working with the switch function on the OB command 1400m / min to 1600m / min, is there a problem? - The motor x1 and x2 not the same voltage, it seems to me to have adjusted the screws x1 x2 on the BBox differently. possible problem? - Can openbuild 24v circular LED lighting can magnetize the router clamp. isolate the led lighting of the clamp? I'm looking for all the leads thank you
Check you Grbl Settings, Max Rate. Not your CAM parameters. See Grbl v1.1 Configuration · gnea/grbl Wiki as G0 moves run at that rate, not you cam feedrate
