#KvvCreates, #NextionCNC Home Switch Installation LinuxCNCKent VanderVelden2020-08-18 | Home switches are added to a LinuxCNC retrofitted mill to create a convenient and consistent starting position on startup. LinuxCNC then provides software based hard limits for each axis, preventing collisions with axis endpoints, and verifies loaded files are within the work envelope of the machine. With small inductive sensors, the home switches can be tucked away, protected from chips and coolant. While hardware limit switches are meant to save the machine for an expected over travel, home switches are used every time the machine starts and software can be used to simulate limit switches, especially if the position is driven by closed-loop motors. The home switches are attached a Mesa 7i76e board and the mill is a PM25 CNC retrofit.

#KvvCreates, #PM25MV, #CNCRigid tapping and thread milling on a PM25 LinuxCNC millKent VanderVelden2018-11-19 | Rigid tapping and threading milling are attempted on a Precision Matthews PM25 LinuxCNC CNC conversion. To allow rigid tapping, a spindle encoder is added by attaching a rotary encoder to the top of the drawbar. The differential signals from the encoder are converted to single-ended and then passed to the fourth axis encoder input of a Pico Systems Universal Stepper Controller. LinuxCNC is the CNC controller. With a 2500P/rev encoder, rigid tapping works well at 400 RPM, but the required sampling rate is too high to support 800 RPM. At 400RPM, the stock PM25 spindle motor does not have sufficient torque in the low end with the high speed belt speed to reliably form tap 1/4"-20tpi but cut threads are reliable.
