Problems after firmware update (Ormerod 1)

Hello everyone,

I've updated to the 1.09 Firmware and made the changes following the tutorial but i'm not able to print due to 2 problems:

- The Z axis is too high when i'm printing even if i have set the Z0.
- I can't extrude plastic during printing but i can extrude manually through Pronterface. ( It's saying no tools selected but i have chosen T1 by typing T1 manually through Pronterface)

Here is my config.g :

Thanks in advance for your help !

1. You have this in config.g:

M563 P1 D0 H1 ; Define tool 0
G10 P1 S-273 R-273 ; Set tool 0 operating and standby temperatures

The P1 parameters in those commands defines the hot end as tool 1. The standard for firmware 1.09 is to call the hot end tool 0. So change P1 to P0 in both of those. This will also work better with the default tool settings in slic3r and Cura. Also put a T0 command in your slic3r start gcode, if you don't already have one. This will hopefully get extrusion working during printing.

2. You say the Z axis is too high during printing. Do the files you are trying to print have a G28 command near the start to home the printer? If so, then your manual setting of where Z=0 is will be lost when the home command is executed.

I have the same problem.

I have the original Ormerod 1 printer and had to be sent a new Duet PCB, which is now updated for the Ormerod 2. Since this I have not been able to do a print as the extruder will not work, nor can I successfully connect via web interface or Pronterface.

I've tried so many different combinations of firmware and can't get anything working.

Whenever you change firmware, you MUST use the SD Image files supplied with that firmware; if you mix different versions of SD Image and firmware, it may cause unexpected results. See: [reprappro.com]

I've updated the commissioning instructions to reflect firmware changes. Understanding how tools are configured, and how to enable them (which will get the extruder working), are covered there. See: [reprappro.com]

Generally, after switching on the printer, you need to enable the correct 'tool'. As dc42 says, your firmware is set up to use 'T0', which is now standard, so send 'T0' to enable the hot end. In firmware 1.09, extrusion is not allowed if the hot end temperature is too low; ie cold extrusion is prevented. You can override this with 'M302 P1'. This is covered in the calibration instructions, here: [reprappro.com]

Make sure that gcode files you are using do not change the tool number from T0 to T1. This will be early in the gcode file. You can edit this in the gcode file directly. Check your Slic3r settings (or use our latest profiles), that T0 is the enabled tool. This is usually set in Slic3r > Printer settings > Custom G-code > Start G-code, so that any gcode you generate uses the correct tool. We changed the first tool to be T0, from T1, in the v1.04 firmware release, as that is what everyone else uses.

Your Z height is set very high: 'G31 Z5.3 P619'. I'd normally expect the Z[value] to be set around 2 to 2.5. Check the Z height calibration, here: [reprappro.com]

As dc42 says, if you set the Z height with G92 Z0 manually, but still have G28 (home all axes) in you gcode file, this will home the axes using the figure set with G31 in the config.g, and override the manual setting.

Unless you've changed the Y axis ends, and put the microswitch of your Ormerod 1 at the other end of the axis, continue to use the sys folder for Ormerod 1; don't use the Ormerod 2 sys folder. Also, the Ormerod 2 expects a 4-wire modulated probe, rather than the 3-wire probe shipped with Ormerod 1. If you have not updated the probe, and use the Ormerod 2 settings, you'll probably get erroneous readings.

Firmware release notes are on our blog/news. I'll add links to these to the firmware update instructions. The last few are:
v1.09 (1st May 2015) - [reprappro.com]
v1.04 (16th March 2015) - [reprappro.com]
v0.78 (3rd July 2014) - [reprappro.com]
v0.65 (20th May 2014) - [reprappro.com]
