There are a number of ways to use the Touch-off Plate. This guide will go through one useful method, for Z-offsets only.
First, attach and connect the touch-off plate.
Mechanical attachment on the print bed is achieved with the outer-most screw positions. (Other holes are for use with other setups such as the dovetail bed or rotary vise). Tighten the screws finger-tight so that the touch-off plate is firmly clamped to the bed.
Connect the 3-pin connector to the mating connector on the back of the base of the machine (behind the X-bellows):
If you plan to leave the cable in place when the touch plate is not in use, make sure you route it along the back of the base casting so that the X-bellows covers do not scrape across it (as shown below). It is not recommended that you leave the touch plate attached to the bed when running the machine, especially during milling cycles. Chips and dust will interfere with proper function of the device.
Confirm that the "E4_STOP" LED is ON, then turns OFF when pushing the pin of the touch-off plate:
On the "Offsets" page, the Z(↓) button will run the Z-axis down until the touch-off plate is hit (or a maximum of 10mm, whichever comes first).
Here is one possible method:
- Pull up the Probe (T10)
- Jog to just above the touch-off plate pin (approximately 5mm above)
- Run PROBE Z macro
- In offsets page, set an unused WCS to active (59.1 in example)
- Set Z value of WCS so that curent Z value is 0
- Jog machine up to a safe height and select tool to be calibrated
- Jog machine so tool is just over touch-off plate pin
- If additive tool, make sure nozzle is completely clean where it will contact the pin
- Run Z(↓) probe cycle
- In Offsets page, adjust Z value of Tool Offset so that the current Z value is 0.
- Repeat for any other tools to be set
- Jog to safe height
- Remove touch-off plate
- Return to previous WCS (generally G54)
