Thank you for this video! I was inconsistent in the order I changed tools resulting in work being destroyed. Having the content of your video made all the difference!
Hello and thank you for an excellent guide to the tool setter process. I'm new to all this and it has been a great help. I thought I would share one experience with the set up process which befuddled me for a day or two. I found no reference anywhere to the problem I was having so I hope this will helpful. My setup includes a vacuum work holder table. My cutting tool was always off by about one millimeter in depth. I reviewed the set up process, checked work piece thickness etc to no avail. I also checked all Masso settings. Finally it occurred to me that I was turning on the vacuum after probing the thickness of the work piece. The vacuum was compressing the table rubber gasket and lowering the spoil board by about a millimeter. So lesson learned, turn on the vacuum before probing!
Hi peter, another great Masso video. I think that your table on the machine must be non conductive if the circuit you showed is enabled.On an all metal machine the block would close the circuit if the metal plate is sitting on it the table. The block needs to be connected to the negative of Masso and the positive to the tool. The commercial Dog River Tools achieves this by having a positive and negative running to the block and a fly lead from an insulated block terminates on an alligator clip that is attached to the tool. In that way the isolation is achieved. Cheers, Richard
Hi Richard, I'm afraid i have to disagree with you on this one. If my table was conductive I would put a non conductive layer on the bottom of the block. eg glue plastic to the bottom. For safety the table should be grounded to earth and since some power supplies have their -ve grounded and Masso uses -ve ground it is reasonable to assume you would ground your machine to the -ve and not +ve as you suggest. cheers Peter
If you get a tool setter with the over limit switch, make sure you get the normally open one. If you get a normally closed device, you can invert the signal for the tool setter input no problem, but you won't be able to combine the over limit side of the switch with the Stop Cycle button because that is normally open. Combining the 2 cancels each other out and there's no way to assign another cancel cycle button to an input.
Very informative!! Great job. You've convinced me to go with Masso on my next CNC build. I've built 2 some far. Both use conventional PC based boards with Parallel port connections. I use the same PC for both machines. So, swapping between the two is a real pain in the ass. Do you have a video that talks about setting the "resolution of the ball screws", i.e. commanded travel vs. actual travel?? I will probably swap one of the machines over to Masso in the new year. Thanks for the very informative info.
That video does exist. It’s pretty straightforward. There’s also a wizard In Masso in case you don’t know your specs. There’s even a backlash setting in case you need it. I can’t wait to get my Masso...
Hello Peter, your videos are really inspiring! I'm planning to build my own plasma CNC machine with messo plasma CNC controller. What do you think is it easy to set-up as a newbie?
Should be fine if you make one video with instructions how to calibrate the axis with masso ! Thanks in advance -only this stopping me to buy masso ...
PS. I said the below . because of the possibility that Masso and the earth of the machine are coupled. No on reflection I may be wrong. Please apply your thoughts to this, cheers, Richard
Hey Peter, How does Masso actually calculate the tool length, do you have to use tool probing with it as well in order to calculate that? what happens if you move where the tool setters location will this mess up what the tool length offsets are?
Do you have a video showing how to install closed loop stepper motors to the masso controller? If it's the same process and an open loop and you have a video can you share the link please. Thanks in advance.
Was the choice of 5k6 resistor purely because thats what you had. I cant think of why the pullup cant be anything as long as you dont exceed current input.

Another awesome video. I would really like to see more of the probing stuff.

Wow great tip!! Thanks!!
Really appreciate the video. A lot of great information you have a blessed day
Thanks Tim
Well done again Peter. Thanks from Ross.
Thanks Ross

Hi Richard
Just saw this reply after I replied to the first comment. I agree the -ve grounding is why you would not use +ve.
Cheers

Peter, what is the recommended wattage of the 5k6 resistor? Thanks for the easy to understand videos.
it doesn't matter as this is a logic levels. Use a 1/4 watt not because you you need it but because they are common.
Cheers
Peter
Is it possible to adjust the feed rate on the mdi screen?
If so, I would like to know how to do it.
Thank you.

Well, at 24v the 5,6 k gives the needed 20mA - it is not criritical butit shouldnot too low
What is the cable? Mine didn't come with one.
Just wondering why you use the resistor? Will it work without it? What happens if you don't add a resistor?
Without Resistor you make a short circuit and the masdo fuse blows (and/or the optokoppler is killed)
what is the wattage value of the resistor?
1/4 watt will be ideal.
Cheers Peter
My probe doesnt work when my bit is in the spindle. It registers when the bit isn't in the spindle. I swapped the wires and same issue. Any ideas?
