Great video, could have used this during week , thanks for the help setting the homing on my machine. Excellent support. Had to invert X axis and set at X 950, worked well. Z axis caught me out as travels are back to front, Z axis is a minus setting. All good now.
Are the sensors shown safe to use with coolant? Are they waterproof? Thanks for the video very informative - great to see you regularly uploading instructional content.
For a dual driven gantry cnc router, does masso allow for independent homing in order to square up the gantry? Thanks and keep up the great video content!
hi, i just got my masso controller last week and just booth up yesterday, and have some question about the axis calibration of z because if i home the z it well home at top 0.00 position. how i can calibrate it i need to put (-) on the value of my z? example if my z axis is 150mm travel i need to put minimum at 0.00 and -150mm on the maximum? thanks Rex Cobey
One area to be careful is that Masso does not support any hardware limit sensors or switches on the other end of each axis--opposite of the home sensor end IOW. This is an unacceptable oversight IMO. We had the same situation he showed in the video where on an initial home sequence one of the axis's was inverted. In our case it was the B axis which is slaved to Y which resulted in the ends of the gantry moving in opposite directions. Even getting to the estop fairly fast we trashed two ball screws and ball nuts and had a 10 day delay waiting for replacement parts. My point is that even cautious reasonably bright people make mistakes and there should be provisions on the other end of each axis (excluding Z obviously) for limit sensors as insurance. Masso does not agree (and some users might not either) as they push using the software limits. If I had known this before our purchase I think I would have gone with a different solution as machine and worker safety is important. To be clear I am not knocking Masso as their service has been good so far and I think they just don't agree that there should be limit sensors on both ends.
Gene Phipps I am not sure how the addition of limit switches would have made any difference in your case. Neither axis would have gotten anywhere near a switch of any kind before inflicting the damage you describe. As you said, you made a mistake - you should have checked the motor direction, individually, prior to attempting to home the system. As for you complaint of a lack of action by MASSO is a bit rough, Jatinda has made significant and regular updates to the MASSO software based on customer feedback. Yes, the software still needs some improvement but as the entire product is the work of one man we have to be realistic in our expectations. Personally I would vote that MASSO is the CNC hardware product of 2017, the software interface not so much so, but it is a wonderful foundation to build upon.
I actually used our example to demonstrate how easy it is to make simple mistakes that could lead to serious damage to either the machine or workers nearby--I was not saying limit switches would have prevented the damage in that particular case, but rather mistakes WILL happen. You mention frequent software updates and I agree that that is great--but the updates themselves also have the potential to cause an issue that could damage the machine or again injure a worker. There is simply no excuse for the system to not support hardware limit switches. To me it is like intentionally driving a car with faulty brakes. I also went out of my way to mention that Masso support had been good. I was not knocking Jatenda. For hobbyist CNC users Masso is wonderful. For a production shop with employees I would have concerns.
Thanks for feedback and every feedback that a MASSO user gives is always added to our feature request list. We do plan to add the features over time, its just that the list is very long now with common and personal feature requests. Again something like this will be added in the future because we still have a lot of inputs and other resources available on the MASSO. We will for sure look into this and see if this can be pushed in the next software release. Thanks for the feedback.
Hey Gene, I know this is a very dated reply and things may have changed in your situation and also many things have changed in Masso but the best option for a hardware limit switch is to have the extra limit switches on each axis and run them NC in series with each other through the E-stop input. This would cause an immediate shutdown to prevent damage in any case. There are many other alarm inputs now (more than likely not implemented at the time of your post I understand) that you could wire into. I do agree there is many more features that could be included within Masso but that is just a very easy example of how to remove any danger of damage from hitting a limit at the wrong end of the axis :-)
More,more ,more,MASSO videos. Thank you for sharing .
he Raul, always so good to hear from you. I hope you like the videos. Please share these on facebook and other places, thanks.

This video sold me. I just ordered my 5 axis Masso
thank you

yes you have to watch them getting any coolant, will need covers to protect them. Thanks and we hope to keep adding more videos each week
Good video my milling machine as all the swichis I just do,t know how to wire them?

Thanks Benjamin and yes you can slave the axis with an option to have two homing sensors on each side to square up the gantry
hi,
i just got my masso controller last week and just booth up yesterday, and have some question about the axis calibration
of z because if i home the z it well home at top 0.00 position. how i can calibrate it i need to put (-) on the value of my z?
example if my z axis is 150mm travel i need to put minimum at 0.00 and -150mm on the maximum?
thanks
Rex Cobey
yes set Z minimum to 0.00 and maximum travel -150mm
IT'S WORKIN IN NC STUDIO ??
Can the amount of offset from the limit switch be changed.
Chris Bailey you can set the pull away the pull away distance in the Masso.
yes you can set a pull-off distance
The sensor need 5 volt is there any available 5 volts on the masso or I need to another 5 volt power supply?
Hi, you will need 5v for a power supply
