Can you wright more than one line of G-code in MDI?

In MDI I can't seem to get masso to read a feed rate when typed in.any suggestions. I noticed that my x axis don't have a zero button in the corner like on the z axis, so how is the best way to zero the axis with out homing the axis? I have the lathe version.

I have encoder to put on my spindle it is a Acu coder it has a output plug with 10 pins how many input wires do I need for the masso. Sending pic of encoder. Thanks

What command are you typing into MDI?

How have you formatted the command?

More info on the encoder is required.
  • Maker's name?
  • Model number?
  • Any documentation you have.

Unless we have the same encoder in our hands we can't help without documentation.

Regards,

Arie.

PS. How is the X axis calibration going?

Not to good, I jog the axis it goes in the right direction, when I home the axis it goes in the right direction, but when I MDI the axis goes in the wrong direction. I got the z axis calibrated and everything goes in the right direction.

When I try to MDI a feed rate I just type Z-6.0 inches F2.0. I don't understand the formatting thing? I would like to be able to MDI a feed rate to try a test cut to check out my motors under actual cutting conditions with using a gcode prog. because I don't have a post processor yet.

Thanks

Right click on a blank spot on your software computer screen / new txt document / re-name it / open it / write your G Code lines there /save it / WIFI it to the Masso or put it in a file called PC Files on the USB stick / F6 load file with the Masso.. Note file structure may be slightly different if you have a G2

Try this for G Code formatting (the following is a straight line on X axis w/ 10" of travel & a feed rate of 100 ipm - change as needed a "-" between the Axis letter and number will give you minus travel):

G01 X10 F100

You need to place MASSO into feed rate "condition/mode" and you do that with a G1 command, you only need to do that once until you "overwrite" that with another G command that can change the feed rate. ie.
  • G1 Z-6 F2
  • X5 Z-2
  • X7 Z-4 F3
  • G0 Z0

The first command set the feed rate at 2 inches/min and moves the Z axis to -6. Next moves X & Z to new location, still at 2 in/min. Next moves X & Z to new location, but at 3 in/min. The last command overwrites the feed rate to the rapid rate of the machine.
because I don't have a post processor yet.

  • What CAD program do you have?
  • What CAM program do you have?

Fusion 360 is a CAD & CAM program in one and it is free for personal use. There are plenty YouTube videos about, on the use of Fusion, one channel that has posted lots in past few months is Autodesk Fusion 360

Arie.

Hi Jim,

If the tool moves in the wrong direction when using MDI then you need to go into the tool table. Select the tool and either add or remove the check from the "Tool on back side" for the tool you have loaded.

It will reverse the tool direction when you use MDI.

Make sure your X + & X- are as shown in the screen.

Cheers Peter

Thanks to you two for all your help. Does masso make a pendent just for the lathe or do you use the same mill pendent. I made some chips today so going in the right direction.

There is no dedicated pendant for Lathe. You just use the standard one.

You could make a custom one if you wanted. The pendant circuit is available in the documentation but I recommend you buy the pulse generator from the Masso shop as that is the part that catches people out. Only certain types will work.

Cheers Peter
