New elite foreman owner. Table build and setup complete. Have reloaded masso software and triple checked motor dip switches and still have the following issue:
X-axis only travels about 9.5” before a soft stop and masso readout says it traveled a full 48.0312”
Y-axis travels 29.7” before a soft stop according to Y readout on screen (though the “machine” readout says it traveled 48.37”)
I can “trick” it by adjusting the “Motor: distance per revolution” adjustment for each axis on the F-1 screen to move farther but don’t know what I would need to set it to to make it accurate, so I put back in the factory setting bit at least confirmed the machine can travel the full length physically.
The F-1 x and y axis factory setting are identical for M:DPR (0.62990) and D:PPR (2000) and feedrate (600) but only slightly different for acceleration. This is odd to me as the x axis is much more diminished in travel distance than the Y.
Lastly, the speed of the y axis is about 2 or 3 times speed of x axis in continuous mode.
Haven’t been able to find a solution on line…can anyone help? My heart is aching to make that first cut!
Thank you for your continued assistance. I reloaded the software, rebooted, and attempted to HOME. The following errors occurred (photos provided). I repeated this process a second time with the identical errors.
After hitting the safety stop and resetting, I could jog the spindle in continuous mode. Jogging the X it moved 24” as shown in the upper left of next photo but the machine readout on right shows 48”
We can do some basics, and start ruling things out.
Check that all ball screw/motor couplings are tight.
Check that all homing sensor inputs are LOW in normal state.
Uncheck both Home after… boxes for now.
When you jog continuous, are the directions of movement correct - X+ > right, Y+ > to back, and Z+ > up?
When you home, are the same correct directions followed?
With the longest accurate ruler you have, measure the distance travelled in X and Y when using the MDI to command 200 mm (or some equal " value) - will depend on the length you can measure. I would put painter’s tape down on the table parallel to these axes, and measure using whatever endmill has the sharpest/smallest point. We can see if there is some consistent offset when you try differing distances.
Good and bad news. Good news: machine has finally homed correctly! Bad news: I have no reason why. Was going through the checklist sent by TMToronto and as I was measuring the various soft stop travels with the masking tape I would need to reboot (maybe 15x total this morning?) as various alarms would pop up ( sensor and motor alarms for x, y, and b but nothing consistent…random each time. (All of this after re-cabling all masso inputs). 1/3 of the time the F1 screen would show all “low”, 2/3 of the time there would be 1 or more “high” but also random as to what was high amongst the motors, sensors, and twice also on “input 23” which is blank.
Homing would not result in the “machine distance box” on the right hand side of the F3 screen to show x or y at zero (but z would be at zero). As I was rebooting and marking distance traveled before a soft stop failure to try and find some consistent ratio for the movement, on try 15 suddenly the masso machine distance zeroed correctly, and now the gantries do move the full distance. Have rebooted and it worked correctly 3x in a row now. I hate I cannot post what the “fix” was but I’m going to take the win and try and get a spoil board on and flattened today. I appreciate so much this group and the comments provided.
