Hi All

Been away for a few years, trying to get my Ormerod up again...
Running into all sorts, would appreciate some guidance.

Got some old downloads for firmware and www interface. Unsure of the version of either the software or the hardware, but was under the very first RS models.
Spending lots of time on the internets, but lots of conflicting information, hence I decided to come to the forum.

Update: FIRMWARE_NAME:RepRapFirmware FIRMWARE_VERSION:1.00o-dc42 ELECTRONICSuet (+ Extension) DATE:2015-03-06
WWW HTML: 1.11, JS: 1.11

A few questions if you dont mind:
'reprappro.com' not able to get the original build docs?
Which version of the Firmware, and web interface should be used, please note no modifications as yet. I have DC's IR sensor I think... :-), oh and where could it be found.

Progress:
Currently got the printer built from memory..
Bed mdf badly warped, would be looking into some other solution for this.
All axis and heaters responding to Pronterface.
Trying to get the y-axis compensation set up, no luck.

Currently not able to run G32, pronterface responds with a stack dump as below. Following this guide I found ormerod_autolevel_calibration

Quote
SENDING:G32 [ERROR] Can't read from printer (disconnected?) (SerialException): call to ClearCommError failed [ERROR] Can't write to printer (disconnected?) (SerialException): WriteFile failed (WindowsError(22, 'The device does not recognize the command.')) [ERROR] Can't write to printer (disconnected?)

(SerialException): WriteFile failed (WindowsError(22, 'The device does not recognize the command.')) [ERROR] Disconnecting after 4 failed writes. Disconnected.

Connected to the web interface but getting ajax errors once i navigate to the settings section as follows:

Quote
Communication Error An AJAX error has been reported, so the current session has been terminated. Please check if your printer is still on and try to connect again. Error reason: SyntaxError: JSON.parse: unexpected and of data at line 1 column 1 of JSON data

I did check to see what the response look like but there is no response to the rr_config call.

Any help or guidance please.

Thanks

A few suggestions:

- There is currently a mirror of the Ormerod documentation at [reprappro.cheeseandham.me.uk].

- Your firmware is very old. You can find more recent firmware at [github.com]. Some Duet 06/085 users have found that in recent releases, you need to set a static IP address for the network, because if you set the IP address to 0.0.0. to use DHCP then the Duet gets stuck in a reboot loop. There is a possibility that this is fixed in the latest 2.01 beta, but nobody has yet reported to me whether it is or not. I have never been able to reproduce this problem.

- You will need to make some changes to your config.g file if you upgrade to recent firmware, in particular you will need to add a M574 command to define the endstop types.

Hi DC

Thanks, always helping as I remember...and thanks to whom ever is hosting those docs... life saver.

Uploaded the new Firmware as per your direction, and all seems well. Able to get the web interface up with no more issues.

Now running as reported by Settings on the interface:
Firmware: RepRapFirmware 1.09 (2015-04-21))
Web Interface: HTML: 1.11, JS: 1.11

So now I am moving on to get the bed level and getting that y-axis compensation set up (G32) to work.

More questions,sorry.
A little guidance on the M574 command around the end stops. I have not modified the printer yet, so it should be default. Have the IR sensor which I bought from you, but have not installed it as yet.
On the settings side, what do I need to change from the defaults now loaded from github?
If someone has example Slic3r settings for the Ormerod 1, that would greatly be appreciated?

Thanks
Madmob

If it's any help, here are my config.g settings for the Ormerod 1. It has a Duet 2 Maestro controller in it instead of a Duet 06 now, but most of the settings should be the same as for a Duet 06 except for M305.

The modern way of doing bed compensation is to use G29, not G32. If your Ormerod has bed levelling screws, you can use G32 to have the firmware suggest how much you need to adjust them. See [duet3d.dozuki.com].

The M307 setting in config.g were obtained by tuning the heaters using M303. Your values may differ.

There is currently a mirror of the Ormerod documentation at [reprappro.cheeseandham.me.uk].

I notice that some pages have tabs, which don't work due to some javascript that didn't get scraped at the time.

If you need information from these tabs (example: tabs that state "FIRMWARE V1.09 AND LATER / FIRMWARE V1.04 AND LATER / FIRMWARE V0.78C AND EARLIER" on [reprappro.cheeseandham.me.uk] )
then please go to the copy on the web archive , which is much slower than my copy, but does have the tabs working.

Web archive copy is at [web.archive.org] and is the most complete copy of the old site - just slow.

@Cheeseandham: I think all the information on the tabs is on your site but it is one after the other. As you read the page you find the instructions sort of repeating and that appears to be the tabs one after the other.

Thanks for all the feedback.

Currently busy updating my config. g with the supplied sample. Some questions if you don't mind.

Found lots of differences with my existing config file, which was expected, but after lots of googling, I had not been able to find any reference to the below mentioned items. Some explanation would be appreciated if possible.

Please explain the difference with the U parameter of the following and also present in M203, M208 and M566.
M201 X1200 Y1200 Z20 E1000 ; set accelerations
M201 X1200 Y1200 Z20 U1200 E1000 ; set accelerations

In endstop configuration, there is once again the U parameter. Here I use the default at the moment for the standard setup as
M574 X0 Y2 Z0 S1 - X endstop at low end, Y endstop at high end, no Z endstop, all active high.
You use
M574 X1 S2 ; I believe the Foil on the Z axis base
M574 Y2 Z0 U2 S1 ; Not sure about this one

On the M305, is the T parameter required and if so, any suggestions as to how to accurately acquire these values.
M305 P0 T10000 R4700 ; set thermistor for BED

I assume the following is only relevant for dual extrusion, the second value being the second extruder?
M92 E420:420

Will report back with progress

Thanks
MadMob

1. You can remove the U parameter from all the commands it appears in, I added it when I was simulating an additional axis.

2. The T parameter defaults on the Duet 06/085 build are correct for the Ormerod (10000 for the bed, 100000 for the extruder).

3. Yes, the two M92 E values are for dual extrusion.

For the M305, I used the following as directed:
M305 P0 T10000 R4700 ; set thermistor for BED

This however gave me an error response in the gcode console

Quote
Temperature fault on heater 1, T = -14.7

Note the -14.7, as the actual reading was 14.7 at that time.

I removed both the M305 commands and then it runs fine, all temps do update in the web interface.

Any ideas?

Also something else I found:

Quote

M572 D0 S0.1 ; Pressure advance
M501 ; Read parameters from EEPROM
T0 ; select first hot end

I had not been able to get either of the above to work, yet.

If you have an older Duet 06 board then you need R1000 not R4700.

Thanks to all the helpers out there..

Update:
Got the config.g running properly now, the last item being the Thermistor settings.
Followed your advice DC, and all went well.
Started test print but the fillament did not perform as I remembered... After much testing I found the thermistor values to not be R1000, but R4700 instead... and for some reason this time it worked when I changed it in the config.

Now moving on to the Orthogonal Axis Compensation, hope this goes better than I remember it to be.

After that I will start with the actual printer settings in Slic3r.

Will update as I go along.

Very glad to see some action here again.

I am following with excitement.
