Is there a Pronterface move to .. M code ?

Hi guys, I just got my Mendel90 roughly calibrated and I am getting slightly tired of pressing the -10mm button in Pronterface every five seconds to get my hot end down to the bed (I am using a Max z end stop)

Is there any M code in Pronterface to tell the printer to move to a certain position ?

Thanks heaps

Jeremy

No M code. But you can use the G code. G0 Z# where # is how many mm you want to be above the bed. You can also specify a X and Y if you want to go to an exact location.

Fantastic !!!

- what is the difference between M code and G code ?

thanks so much

About 6 letters.

They both are used to control the printer (or mill, or lathe, or EDM, or whatever). The "G" codes primiarily deal with controling the movement of the bed, extruder, spindle. I think of them as the "G"o commands. The M codes are "M"iscellaneous or "M"achine commands. They control non movement actions and parameters, as well as can provide informational feedback as to the state of the printer such as position and temperature. You can get a long list of the common G and M codes as they pertain to 3D printing here.

Rightio ... I will remember that "G"o !

Thanks so much - im sure that list will come in handy

And if you don't want to type the G-Code every time you can define a custom button in pronterface : [t00tiereprap.wordpress.com]

Hi again CDRU,

I just sent G0Z270 and the z motors make a loud squeal and don't turn smoothly, any ideas ?

Hahahah .. sorry I worked it out - for some reason the speed was too high -- seems to be fixed now

Sorry again hahahah -- all of the G code commands seem to make my motors turn slower -compared with normal pronterface commands (my homing speed is the same as the normal speed ) - ? any ideas


- correction this is only with the custom buttons I have made in Pronterface using the G0Z ... command

At the moment it only effects the X and y commands

Update : It must be intermittent , I just flashed the firmware and z is having the same problem too - its only with the buttons though

Update 2 : its intermittent with all G0 commands not just the buttons I added

Update 3: so what I have found is that I must send a command using the Pronterface control before sending the G code, the home functions do not count

You might want to append a feedrate to G0

Something like G0 Z0 F100

Likely you miss the F. F like Feedrate.

Hi guys - so I sent G0Z0F156, and it worked fine after I homed it

thanks so much

- correction sending G0 F (speed) X (position) works fine the first time

Using G0, F is ignored anyways. G0 means "as fast as possible". G1 is the command which moves at the given velocity.
