Re: Spray Robot

Thanks Tom! I will check it out, a lot of the jerkyness has to do with the mechanics. The entire assembly is 3D printed. In order to make a solid connection between the plastic pieces and the gearbox shafts, I 3D printed an adapter out of steel with a key slot. It was my first attempt to print metal...

Re: Spray Robot

Machine is up and running! I modified the Kinematics program to keep the spray head parallel no as the robot moves in X/Y space. G Code is used to adjust spray angles.

Tom, I am trying attach an MP4 video and am not having any success.

Re: Live Tooling

Thanks Moray, some of the challenges I have faced is changing the spindle back and forth between running as a spindle and a C axis. Optimally the C axis would be very stiff with zero backlash. When running as a spindle the high high RPM is the target. I have been looking for a company that makes two...

Re: Live Tooling

Thanks Tom, I have a part chucked up in a lathe, with the spindle configured as the "C" axis where I can control the rotary position. I have an end mill on the X/Z saddle of the lathe so I can plunge it in and cut arcs in the face. I am not particularly familiar with lathes, I know G96 will keep the...

Live Tooling

Greetings, I have a lathe controlled by KMotionCNC, and am wondering how to set up up the spindle with live tooling. Imagine cutting an arc with an end mill on the face of the spindle (C-Axis). How do you set up the feed rate for cutting that arc? Obviously the larger the radius the farther a given ...

Re: Spray Robot

Tom,

Spray booth is built, looking at making several more of these robots. As far as installing this software on multiple computers, I do the normal install with drivers, and then just replace folder with my library instead of the one that installs with KMotionCNC?

Thanks,

Scott

Re: Spray Robot

Tom, This looks great, I am getting very close. I am trying to understand your code a bit better. // adjust xy to be zero at neutral home position x = -x + L - S; y += R3; I can see why we would need this the first time through, but doesnt forcing the X/Y variables every cycle mess up the actual pos...

Re: Spray Robot

Tom, All the hardware is here, and I have been building this robot but am having some problems. Here is what I have done so far 1. Made an INIT program and calibrated each servo motor 2. Made a homing program - homes to a hard stop, and then moves motor 1 to 0 degrees, and Motor 2 to 90 degrees This...
