5axiskins tool offset

5axiskins tool offset was created by AndrewL
How do you apply a tool offset to the 5axiskins so that the machine will rotate around the tool tip?
So far, this is what I'm trying on a mostly stock "Sim-5Axis Bridge Mill (xyzbc)" config.:
[HAL]
HALCMD = net :tool-len motion.tooloffset.w 5axisgui.tool_length
# HALCMD = net pivot-len motion.tooloffset.w 5axiskins.pivot-length (this will not work)
HALCMD = setp 5axiskins.pivot-length 200 (This alters the right parameter but will not adapt to a tool change)
Then G Code:
M6 T1 G43 (With some W offset in the tool table)

the Standard tooltable ofsets shoudt work no need to apply offsets by W axis
what kinetics are you using the 2.8 master got a new kinetics file for the 5axis standard AC BC

Switching kinematics between 5axiskins and trivkins may be a solution. I wanted to begin by using the halcompile to load some kinematics from:
github.com/LinuxCNC/linuxcnc/tree/master/src/emc/kinematics
However, when I try this in the terminal, I get errors. What is wrong?

I found that halcompile does not handle kinematics files well. You might want to try the proper build process.

the switchkins shoudt be part of the new 2.9 as so many of the 5Axis mashine users like to use it

At some point, I don't know when, my 5axiskins stopped working properly. If I create a generic vismach 5axis bridge mill configuration the vismach simulation moves as you would expect but x (joint 0) and y (joint 1) are no longer are coordinated with C in 'AXIS'. Any suggestions as to where to find what went wrong?

Hello, were you able to solve the tool compensation issue in 5axiskins? I also find myself stuck there

Have you setup your hal to add the tool_offset to the pivot length?
See '/axis/vismach/5axis/bridgemill/5axisgui.hal':
See '/axis/vismach/5axis/bridgemill/5axisgui.hal':
loadusr -W 5axisgui
# to set different pivot_len, use:
# 'loadusr -W 5axisgui pivot_len=value'
net :jx joint.0.pos-fb 5axisgui.jx
net :jy joint.1.pos-fb 5axisgui.jy
net :jz joint.2.pos-fb 5axisgui.jz
net :jb joint.3.pos-fb 5axisgui.jb
net :jc joint.4.pos-fb 5axisgui.jc
net :jw joint.5.pos-fb
net :jy2 joint.6.pos-fb
# Note: no joint or motor connections are used
# for the w coordinate
# compute pivot-length needed for 5axiskins
# according to gui pivot_len and tool z offset
loadrt sum2 names=pivotsum
addf pivotsum servo-thread
net :gui-pivot-len <= 5axisgui.pivot_len
net :gui-pivot-len => pivotsum.in0
net :tool-len <= motion.tooloffset.z
net :tool-len => pivotsum.in1
net :tool-len => 5axisgui.tool_length
net :pivot-len <= pivotsum.out
net :pivot-len => 5axiskins.pivot-length
net :tool-diam <= halui.tool.diameter
net :tool-diam => 5axisgui.tool_diamPlease Log in or Create an account to join the conversation.

Thank you very much for answering, Here is what I don't understand, in my model I don't get those configurations. In the configuration that you sent me, I understand that it is from a vismach and if I put it as it is in my hal file, it will not work, so what letters or parameters should I modify? (Please help, I am very new and forgive my English, I use Google Translate)
