I have a onefinity elite woodworker equipped with a tool setter and a RedLine spindle.
Whenever I start the machine, I home it and naturally it goes to the tool setter. Then, I load the tool I need for the job and I zero it (x, y, and z). Then, when I press go for the job, it probes Z on the tool setter and offsets the current Z zero value… This has caused me numerous failures, because sometimes the ‘new’ tool is shorter than the tool that was originally in the collet.
Should I change tool before homing the machine at startup ? This process seems confusing. Thank you !
TLDR ; Z-zero gets messed up after homing due to auto-probing with a new tool. Should the tool be changed before homing to avoid this?
Following this. I am setting up my machine soon and I’ve been looking for a correct order of operations from people on the Masso with tool setter. It should be a black and white checklist that is repeatable, but I’ve seen so many videos where people do it differently and I’ve heard countless stories of the spindle plunging into the tool setter. There should be a repeatable process for how to start and would like to hear others successful checklists for this
Don’t change the tool unless asked to do so by Masso. From your description it looks like you are changing the tool to one you use for probing after the homeing. If you change the tool and then probe for xyz, Masso will give you the incorrect results because it thinks that there is a different bit in there.
If you need to change the bit out to one that matches your probe setup, use MDI to enter and run T5M06 (Replace 5 with your tool number). Masso will then ask you to change the tool. Once changed hit cycle start and it will go measure the new tool and you can then probe for XYZ
After seeing comments come up all the time about Z-issues. I get the impression there are two types of users. Both seem like valid ways of operating the machine, each with their pros and cons.
Those that set each of their tools as different tool numbers, and Masso keeps track of them and their offsets in the F4 screen.
This is more inline with how Masso intends for users to use the machine. It’s yet another complicated thing to wrap your head around while learning the machine. This method is needed for using an ATC, or any program that uses multiple tools in a program.
I suspect most advanced user will use this method.
and
Those that change cutters, but don’t tell Masso it’s a different tool number. Masso always “thinks” tool #1 is loaded all the time, but it’s actually different cutters.
This is often adopted by new users, as simpler and a little more intuitive to figure out. It does not require changing tools with the TXM06 command in the MDI.
It unfortunately, opens up the door to make Z-errors more common.
A serious limitation is that you can’t use multiple cutters in the same program.
I think lots of users get themselves in trouble when they use a little bit of both systems! They may install a cutter, touch off the tool setter, then a M06 G-code tool change happens, either by the user in the MDI command, or the cnc program, and it messes up where Masso thinks Z=0 is, or doesn’t know how long the tool is sticking out of collet.
