Hi all. New to this forum, so please excuse any duplication of stuff I haven't found elsewhere here. I currently have a Shark HD4 I bought about a year and a half ago, which has been a lot of trouble, particularly with the gantry. I can upgrade to an HD5 gantry, but am thinking about getting the Lead 1010 with a High Z Mod gantry to replace it, as it has a number of benefits, but am concerned about the spindle. I currently am using the HuangYang 1.5kW water cooled spindle with VFD, a 36 V power supple, and a specialized cooling loop that all works great. I like it's noise level (FAR better than the Bosch router, which is what I used before, which is so loud you can't even hear the cutters working, or yourself think, even at low settings), the fact that I can control the spindle speed easily from a Buildbotics controller (great controller, btw, and yes, I tossed the Shark controller - it's obsolete garbage), and the lack of mess due to not having a fan blowing dust all over. Also, the VFD means the spindle power supply is isolated from the controller, which I prefer. However, is this spindle going to be too heavy for the Lead 1010? Is there a mounting bracket that will fit it (80mm diameter)? I can't tell what sort of mount the Lead comes with the 1010 comes with. I see people talk about a Makita spindle, but it appears to not fit the Lead 1010 mount, and I don't know how it's speed is controlled ... I like using the VFD, even if it's a bit more complex. Can anyone comment about those issues with the Makita on the Lead 1010? I've seen some square air-cooled spindles out there that look interesting also. Would those fit the 1010? Anyone have experience with those? Is there another Openbuilds design that would be a better fit? As far as the spindle goes, as long as it's quieter than the Bosch, has the power to cut hardwoods (as in 2000+ Janka), fits the system without my needing to machine parts from aluminum, I'm not hooked on water cooled. Really, the 1010 with High Z upgrade looks really good, but I need to understand the spindle situation a lot better. I am trying to make product, not be a CNC builder/hobbyist, lol, not that there's anything wrong with that, just want to run reliable equipment that all fits together easily without having to create mounts and the like. Help!!! Thanks in advance. I posted a short version of this on another post before posting this, but realized after that, I think that was too narrow of a description and too few people might see it. So, sorry about that. Thanks again.
