Hello. I have a Workbee 1515 with a black box controller and running the openbuilds controller. I have been running this since January without an issue. A friend asked me if I could surface a piece of live edge walnut for him and I said sure, no problem. I set the piece up on the table. went into the surfacing wizard. Set my parameters (depth of cut .5mm) loaded it. Zeroed everything. When I hit the run button I got an error code 9 locked out during alarm or jog state(g1 x1279 y286000 z-5) -this error may just be a symptom of an earlier event: Alarm:1 hard limit triggered. Machine position is likely lost due to a sudden and imediatee halt. Re-homing is highly recommended. I did this, then reset my z to zero and then my x and y. I ran the code again and I got the same error. I decided to hit run again without rehoming and it drove the z axis down about 1 cm. I stopped the program and re did everything multiple times (definition of crazy is doing the same thing over and over hoping for a different outcome). My wheels are snug, My connectors are tight to the motor and the leadscrew. My electric connectors are sound. $1=255. If anyone has any suggestions, I sure would appreciate it. Thanks, Scot.
Did the error pop up right after starting the spindle? If so: spindle creates EMI. EMi created a false limit switch trigger. Limits wiring too close to router/spindle power cables? See docs:blackbox:faq-emi [OpenBuilds Documentation] Sure you zeroed Z correctly? Sure your Z is calibrated correctly? Z axis Acceleration and Max rate tuned to prevent stalling (if stalls on the way up, it will be lowered next time it heads down)?
I run my spindle cable independently from all other wiring. I have ferrite cores on all my cables. All my wiring is shielded and connected to earth. I do not have a dust boot, so it is not static from that. I absolutely zeroed the project correctly. I have not moved anything and I have not changed anything. No red lights on my blackbox. Checked the cabling with a meter and no broken wires. All of my connectors are tight as are the screws holding the wire into the connections. my acceleration is set very modestly as I am not a production shop. I have done about 50 projects on this machine and have not had this issue before, it just started doing it. Thanks for the guess as I am stumped.
I think I found the issue. The piece I am trying to surface is about 2 inches thick. I have a .75 inch MDF spoil board and I have the aluminum channel flat on the base of the machine. When I hit play, the z axis is rising and hitting the limit switch. Somewhere in the settings, there must be a setting for a safe travel height. So with everything stacked up plus the safety height, it is limiting out. Does anyone know where the safety height setting would be?
Thanks Peter. I am humble enough to have the basics pointed out. Sometimes it is the simplest things that you overlook and you just need a reminder.
The built-in wizard in CONTROL has a hard-coded 10mm clearance Use the Gcode editor tab to find/replace the "G0 Z10" lines with something less
Can you tell me if you figured this out? I am running the Lead1515 and having the same issue you described when trying to carve a piece that is 1-1/2" thick
Yes. I had to rearrange my bed so it wasn't as thick. I had my extusions too high so with that, the .75 mdf and the thickness of the stock, once the safe z hight was taken into consideration, I had run out of travel.
Thank you for responding. I too run 3/4" MDF for my spoil board as that was what I had available when I got to that stage of the build. Guess I will change it to 1/2" when I replace them.
