Guy's i'm looking at my renishaw probes , i'm not sure if i am seeing this correctly but apart from decoding the stream , i'm seeing when not touching the probe emits a signal at about 150khz. When it senses touch it goes up to 160khz. but at the moment i'm not sure , as the only ir detectors i

A pin created by a python userspace component can be linked to a signal with the "net" command, just like any other HAL pin. The documentation shows that Python Userspace Components create pins: http://linuxcnc.org/docs/2.7/html/hal/halmodule.html .. but it does not explicitly state to "net" the

Hi, I'm trying to control an axis position using an user space Python script, but I don't relay understand the Python hal library. So, I want to use Python to periodically set the command position of an axis (3 in my case) based on a sensor read out. To do so I disconnected

I'm surprised you can cut XL pulleys with a hob. It does not look like the teeth are right for that to work.If I had to make an XL pulley from scratch, I'd guess the best way would be to use a 4-axis machine and a ball-end mill. That is one reason I'm wanting to add a motor to my rotary

Actually drilling the timing belt is not a bad idea. The older MXL type belts used a trapezoid tooth belt but the new high torque "HTD" Designs use circular profile teeth.They really are bater and transmit more torque with less belt tension required. Even newer designs are GT2 and GT3 and
