Ormerod 2 bed sensor

Ormerod 2 bed sensor I seem to be having problems with the sensor used to set the nozzle zero height above the bed. I recently made a change to the bed configuration in that I have fitted fitted a GeckoTek Build plate instead of the 3mm glass plate. The GeckoTek is a 0.9mm stainless brushed steel plate with lacquer finish. I am still using white labels at the four corners so as far as the sensor is concerned it is the same as before. The problem is that I have to re-zero the bed almost every print, it is at it's worse with high bed temp when printing ABS. Could it be that the temperature is affecting it or do the sensors need replacing from time to time? Thank you for any advice you can offer.

If the bottom left corner of the board is position (0, 0) then other points on the board are at the following (X, Y) coordinates, in mm:

Top right corner (24.0, 17.62)
Mounting hole centres (2.70, 14.92) and (21.11, 14.92)
Mounting hole diameter 2.8

The Geckotec build plates are very good, if anything they are too good. I have trouble removing ABS prints and have needed to slip a knife under them which of course risks damaging the surface, also the nozzle height above the bed is critical, you will need to get that as accurate as possible. I certainly don't mean to put you off buying one though, I have the HT model and love it.]]> Europa Ormerod Tue, 09 Feb 2016 03:36:46 -0500 https://reprap.org/forum/read.php?340,621533,623714#msg-623714 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,623714#msg-623714
you have to mount it on the side where I already prepared the mountings for the big sensor board. In a few days I would either prepare a mounting bracket for my holder or I will do a new one.

I cannot live or at least print without PrintBite. :D However to be fair there are rumours at the German FB groups (and I think they are true) that PrintBite is some sorft of a ordinary FR4 piece. However PrintBite is equipped with a special pattern on the surface and the ordinary FR4 needs to be sanded before you can use it and the PrintBite gives you a pattern..

@dc42 Like I thought, many thanks for the answer. However my Ormerod 1 uses your one piece fan duct. I will check it with a later model if there is enough space to place the PCB underneath your mounting holes. I would do this also for my own design. That would give me the possibility to move the PCB back a little bit. Can you send me an offer to pay via Paypal or will this be done if the batch is ready?]]> Treito Ormerod Tue, 09 Feb 2016 00:47:30 -0500 https://reprap.org/forum/read.php?340,621533,623579#msg-623579 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,623579#msg-623579
As it uses a steel plate, I was planning to use a cheap ps-05n inductive sensor. I use them on my cnc router and they are very reliable.

Am I missing something here?]]> GroundAttack Ormerod Mon, 08 Feb 2016 17:59:29 -0500 https://reprap.org/forum/read.php?340,621533,623532#msg-623532 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,623532#msg-623532 dc42 Ormerod Mon, 08 Feb 2016 16:38:51 -0500 https://reprap.org/forum/read.php?340,621533,623514#msg-623514 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,623514#msg-623514 Treito Ormerod Mon, 08 Feb 2016 15:48:15 -0500 https://reprap.org/forum/read.php?340,621533,623485#msg-623485 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,623485#msg-623485

By the way what do you think of Printbite ?

@dc42 can you please tell me how deep is your condenser? I would guess something about 11mm? Do you provide a mounting bracket for your big sensor boards for the quick-set of the Ormerod 2? Do I need a black paper underneath a PrintBite surface?]]> Treito Ormerod Mon, 08 Feb 2016 11:57:11 -0500 https://reprap.org/forum/read.php?340,621533,623221#msg-623221 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,623221#msg-623221 Treito Ormerod Mon, 08 Feb 2016 06:41:33 -0500 https://reprap.org/forum/read.php?340,621533,623206#msg-623206 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,623206#msg-623206
If you enlarge the image you can see the two IR projecting LEDs to the right and the receiver to the left of centre so that the detection point is in the middle of the board.

You can find the dimensions of the mini board except the height at the end of the fitting instructions at [miscsolutions.wordpress.com]

Thanks I found it already, but where is the position of the LEDs? I would prefer to hit the sensor board in the middle.

Brian I am wondering if it's necessary to make both a mounting option? I would provide a small part for the existing mountings. Also for the Ormerod 1.]]> Treito Ormerod Mon, 08 Feb 2016 05:39:32 -0500 https://reprap.org/forum/read.php?340,621533,623185#msg-623185 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,623185#msg-623185 Treito Ormerod Mon, 08 Feb 2016 05:35:54 -0500 https://reprap.org/forum/read.php?340,621533,623166#msg-623166 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,623166#msg-623166

Am I correct in thinking that i will need to make a new nozzle mount that has the mini sensor on the left hand side so that it can still be used to home the X axis. I assume the X axis printed bit that the old sensor moves across will need to be extended as well as the mini sensor is a wider board with the critical part in the middle.

I am just about to fit my Chinese E3D V6 type hot end which I have printed a mount for but will now need to modify that if I am going with Davids mini sensor.

Many thanks,

Brian

Brian, check out the fitting instructions for the Ormerod hot end board at miscsolutions.wordpress.com. It includes a link to the printable sensor pad for X homing. You should be able to use that or a similar design for the mini board, if you mount the mini board in the same place relative to the nozzle as the Ormerod board would be.]]> dc42 Ormerod Sun, 07 Feb 2016 17:29:40 -0500 https://reprap.org/forum/read.php?340,621533,622909#msg-622909 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,622909#msg-622909 Maybe there is a 3D-Step-file available of the Mini-sensor board? In that case I could do such an adapter within a week. it shouldn't be a big deal that is why I added the mounting holes at one side.
I used FreeCAD to design this part, I could offer s atep-file but I have no given dimensions of the sensor-board.
I prefer FreeCAD as it is free and for many platforms available, but unfortunately the assembly2 workbench does not fulfill my needs so I design my own printer with Fusion 360. It is like 123 but it offers more functions like a very good assembly-tool.
So what file format do you need?]]> Treito Ormerod Sun, 07 Feb 2016 16:07:47 -0500 https://reprap.org/forum/read.php?340,621533,622835#msg-622835 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,622835#msg-622835
I don't suppose you happened to make it with 123D Design, in which case I would love to have the source file so that I could modify it. Alternatively do you have a STEP file of the mount.

Which design do you use?]]> Treito Ormerod Sun, 07 Feb 2016 10:22:16 -0500 https://reprap.org/forum/read.php?340,621533,622723#msg-622723 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,622723#msg-622723
As the person with the probably biggest damage of the X-arm.
If you use the original X-carriage and the slot is printed well so you can freely move the bolt with the bearing you should be able to align the nozzle. First of all it is very important that the nozzle is perferctly angled. Then you have to watch for the bearing and that was my big fault. I did not take enough care. The bearing surface should be in full touch with the X-arm (I ignored it as it seemed to work). Aluminium is weaker than the stainless steel of the bearing so the bearing can make its way into the aluminium.
If the bearing cannot get in foul touch even though the slot is free accessible you have to options: You can exchange the bearing with a bigger one with an outer diameter of 10mm instead of 9mm. However this did not work for me as the nozzle was not angled anymore. Option two: You can add a sort of shim made of stainless steel. In my case I took a metal ruler. The width should not exceed 13mm. For my second Ormerod which will be soon changed Dave was that nice to add some sort of a shim band. I will test and comprae it with my metal ruler. For the damaged X-arm this was the only option as I needed a stable part to cover the groove. The band would not be stable enough for that case.
However meanwhile I have printed some more parts or some more meters of material. I mainly print at the center of the bed. Eventhough the bearing is perfectly in touch with the metal ruler you can see traces of the movement especially at the center. But it looks more like if somebody had washed or cleaned this are. There is no trace of a groove. But it keeps me alarmed. I will never try to run a stainless steel bearing directly on an aluminium X-arm.
Unfortunately my Ormerod 2 died mechanically and electrically before I could finished printing all parts I would like to exchange at the commisioning. It is not needed to replace much parts but I will have to disassemble the printer completly so I would like to exchange the optional parts, too.
My Ormerod 1 is not easy to handle without the sensor boards of dc42. That printer was a hardly task, but it may be nearly finished. Maybe not.]]> Treito Ormerod Sun, 07 Feb 2016 10:21:17 -0500 https://reprap.org/forum/read.php?340,621533,622722#msg-622722 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,622722#msg-622722 Darathy Ormerod Sun, 07 Feb 2016 10:20:05 -0500 https://reprap.org/forum/read.php?340,621533,622713#msg-622713 Re: Ormerod 2 bed sensor https://reprap.org/forum/read.php?340,621533,622713#msg-622713
