- Blade Change
- Blade buckled
...If there is no direct reason to change the blade shape or position, there is a different root cause to the problem that changing parameters WILL NOT SOLVE
...If the results of your tests do not make sense, or the position seems to vary by the wrong amount or wrong direction after making a change, then a serious mechanical problem exists elsewhere. There is no sense carrying on because you cannot complete this setup unless the machine is consistent and reliable

The notches are named "infeed" and "outfeed" to standardise the notch cut on both left and right feed machines

The distance between the V notch blades is known as the separation. This should be temporarily 'expanded' during testing to make the shapes easier to measure.
It is normally around 136-138, so add 10mm on to the existing parameter to make 146-148
...Separating a V notch like this also prevents a lump of the piece falling out which makes it weaker and therefore unsuitable to run through a second time

The simple way to do this is to measure the 'expanded' separation distance and subtract this from the VSEPERATION parameter

IF this is the "first time "setup on the front V notches, the V axis datum should be changed to ensure the machine is set in the correct base position.
IF you are tweaking the values, use VSTARTPOS and WSTARTPOS adjustments:
'''Front V Notch'''
Use the VSTARTPOS parameter
Increasing the VSTARTPOS parameter will make the front notch shallower
'''Rear V Notch'''
Use the WSTARTPOS parameter
Increasing the WSTARTPOS parameter will make the rear notch deeper
Make the adjustment and run again to check
...The VSTARTPOS and WSTARTPOS parameters are only displayed on the Notching tab on later software versions - if they do not exist, they need to be edited in userVariables.mul and this requires a reboot
