Hello all. I'm new here to this forum. I recently got a LEAD 1515 with blackbox and interface. I not new to CNC. I already buit a Plasma CNC mach3 machine that as been working fine for the last 6 years. This time I decided to build a CNC router that I'm going to need for some projects. I decided to go easier this time by purchasing a Complete kit, as the time I spent working the parts needed would be a bit of a time constraint. Finally finished the build and everything is working as it should..., but when i was about to start a small test drive i realised my X axis was not right. When i jog the cut head, Z and Y axis work fine +/- . The X no. For instance if i jog X+ it moves correctly. When i press X+ again it might move the opposite direction althought the information is increase X Value wich is correct. When i go X- it might go - or + randomly. I of course checked all cables and plugs, everything's fine. The spindle was not on or even powered on. So I'm lost. Do i have a bad blackbox driver? Thanks
Did you check your wiring with a meter? I ask because your symptoms are exactly what you could expect if one wire to the X stepper was only making intermittent contact. This link contains information on troubleshooting the short of problems you are having (not just what the title suggests). docs:blackbox:faq-identify-motor-coils [OpenBuilds Documentation] Alex.
Wiring: that is a classic symptom. See the symptoms in section 1: docs:blackbox:faq-identify-motor-coils [OpenBuilds Documentation] Edit, sorry Alex, i missed your reply, but oh well doubly confirmed
Yes I checked for continuity in motors and connected acordingly. All other axis are fine. Unless one x motor is not working properly. I'll try tomorrow to switch x with z plug in blackbox to see how it goes.
This page The page we referred you to for your issue, linked as well, to which you replied that you did identify the coil pairs (note the FAQ page i linked deals with other points as well, not just that one) after which I asked you to return to it and re-read it (note the section on how its either coil wiring order, OR 3 of the 4 wires making solid contact OR to also test your extension cables ). Further down the page is a process to help you test. Note its inside the BlackBox FAQ menu section, thus I referred to it as “the FAQ page” as I already linked it earlier. It is a page dealing with the Frequently asked question of your specific motor issue, which is always wiring in some way Is Section 1 of the same FAQ page. Click the link and read it
