Laser cut Aluminium X-Arm & Rib kits....

Original dxf files for the acrylic parts are, as usual, in the Ormerod github repository: [github.com]
If you wait a couple of days, these will be updated with the Ormerod 2 files.

Ian
RepRapPro tech support

ok, allready found them on github, ormerod master file

Ok i will wait a few days, even do i found them in ormerod master file....
. Would you sugest any new bed support. that can be found on the forums? i think i will have to print one that is more stable.
Ian, again, thank you for all your support and answers

Is it the mdf support platform you are after?

If so I supply an aluminium replacement that is very good.

Another RS Ormerod Mk1 meets the world

Retired now but I used to make....
CNC Machined Mk1 aluminium bed support plates for the Ormerod
CNC machined X-plates and ribs for Mk1 & Mk2 Ormerods
CNC machined bed support arms for the Mk2 Ormerod.
Dual Hot-End heatsink blocks.

I would love to buy it, but i think that just shipping costs more than i would pay to get it cut out here.
But if i have any problems geting it here i will get back to you.
THen i will probably purchase also x ribs.

Thank's

Hi Dave
The parts arrived last week and looking to do the upgrade with them.
Do you have any directions on installing the bed?
Does the aluminum just replace the wooden square bed?
Where does the thin strip get used?

Does the Ormerod 2 use the same aluminum parts?
Thanks again!

Hi

The bed is a direct swap for the mdf part, takes minutes to fit.

The thin steel strip is an option, some users like to run the x axis bearing along it, it's tougher than the aluminium, if using it, degrease the aluminium first with solvent and watch your fingers, the steel strip is razor sharp.


The ormerod 2 is different I believe, nobody has mentioned stability issues yet so I am not anticipating making any parts for it yet.

Another RS Ormerod Mk1 meets the world

CNC Machined Mk1 aluminium bed support plates for the Ormerod
CNC machined X-plates and ribs for Mk1 & Mk2 Ormerods
CNC machined bed support arms for the Mk2 Ormerod.

my kit had a square bed base, the aluminum is triangular.
So I have four screws that now go to three.
Did they change the kit?
Or am I missing something?

Thanks for the steel tips.
Wanted to make sure it was being used correctly.

No nothing missing, the holes for the three point mount should be there on your bed, the three point mount is better as the two outside screws on the square mdf did practically nothing.

It works and works well.

Hi Dave,

Success! We have a upgraded Ormerod 1 with Aluminum bed and X-arm!
Also changed the Z-axis support to the improved version: thingiverse.com/thing:318545
Between the two changes my Z-axis issue is 93% resolved.
Still working on making herringbone gears for the spring loaded extruder: thingiverse.com/thing:318458
Will also make them for the Z-axis motor.
(I already changed the threaded rod to a steel one that I also ran a die along the threads. Waiting on the brass nut to come in post)

The aluminum works, and it does work well.
I was just asking my questions before I began to disassemble.

I also started working on a duel head extruder concept, looking to join the development effort.
Would it be possible to get a heatsink and nozzle block made to specific dimensions?
If so, for how much cost?

Thanks for the parts and for your help!
I highly recommend upgrading Ormerod 1 kits with Dave's Aluminum Upgrades!

Hi

I'm glad you got it all fitted

Yes I have made extruder blocks for a few styles, let me see the design and I'll let you know. For a rough estimate, I made two blocks drilled and tapped for single and dual nozzles and the Cost was £20, yours would likely be the same but let's have a look.

Hi Amsterdamman,

Have you seen my blog entry on dual extruders for the Ormerod at miscsolutions.wordpress.com/2014/07/27/converting-the-reprappro-ormerod-to-dual-colour/ ? Let me know if you have some ideas on how to improve that approach.

Hi dc42 Dave,

Yes I read the blog entries quickly once through and think your on the right track and doing pretty impressive development work!
I'm still very much a n00b in the repper 3D world and am still in my learning curve with my machine.
Is there a list of the requirements for the multihead system?
Limitations of the code or other peripherals?
I am working on a simpler version of the duel head nozzle which I think lends itself to a solenoid actuated 0.5mm lift system.
It should be able to incorporate your designs and end up making a quad four banger nozzle.
I'm making a sketchup drawing of it and will post it shortly.
With the drawings done the basic nozzle dimensions should be determined.
My thoughts are to first use the design as a simple static single head nozzle to ensure it works.
Which is the best thread for the development discussion?

Also thinking the Bowden tube should be removable from the hot end without disassembling the hot end.
Why?
My second filament change left a piece blocking the tube near the hot end and I had to disassemble the entire hot end to clear it.
When I reassembled it seems the nozzle went in a tiny bit high,
(the thermostat didn't want to come back out and the unit was difficult to hold)
so now I have to re-disassemble the nozzle and three days of frustration continue.
Making the Bowden tube removable from the hot end exposes a location of potential clogs for easier maintenance
and removes the need to do a significant tube clearing task.

You guys are doing very impressive work!
Hope I can add a tiny piece to the puzzle...
Kimon

Amersterdamman, I think this thread [forums.reprap.org] is probably the best place to discuss multiple nozzles.

Lifting the non-printing nozzle would help avoid the interference between nozzles that I describe in that thread. I have some thoughts on modifying my dual-nozzle print head to rotate the whole print head very slightly about the Y axis, so as to lift the non-printing nozzle by about 1mm. I could add electronics to control this to my dual nozzle hot end board quite easily. It could either use the nozzle temperatures to determine which is the printing nozzle (provided that both nozzles are printing similar materials), or use the white control wire from the Duet to specify which one should be lowered. The main challenge is to redesign the nozzle mount to support a small amount of rotation, probably with a bearing, and add 1 or 2 solenoids to rotate it against one endstop or the other.

Just a reminder to any that are thinking of upgrading the x-arm on their mk1 ormerod, I have four kits left and this will likely be the last batch made now for this machine.

Aluminium bed plates for the mk1 will be available forever as they are cut to order .

Thanks

If you are on the fence I Highly recommend Dave's upgrade for Ormerod1 reppers! My Z-axis issues ar 98% resolved with a combination of: Dave's aluminum X arm and bed, the extended Z-axis x-arm support thingiverse(dot)com/thing:318545, a new steel threaded rod (I used a die on the threads as well), a brass nut on the rod and a set of herringbone Z axis gears that I modified and will put on thingiverse soon.
Working on adding more extruders and the stronger aluminum X-arm will help for that as well.

Thanks again Dave for your efforts and your upgrades!

Hi Dave,

Just got my Ormerod2 kit in the post today Seems they use the same acrylic X-arms. Seems with multiple extruders the same issues will happen with the #2 as with the #1. Not sure if the bed needs to be upgraded. Anyone have thoughts on the bed or the Ormerod 2 arms?

I'd like to order one of the remaining aluminum X-arm sets please!
Thanks!

From the images I have seen, I think that the Ormerod 2 x-rib may have cutouts in it for a longer tab on the extruder drive to fit into. Can you confirm that? In which case, you may need to print an Ormerod 1 extruder drive body to fit the alu X arm kit, unless you can cut the slots in the x-rib.

The notches appear to be identical. Unless I was sent a Ormerod1 X-arm ?? I'm in no rush as I haven't even started to print it yet. Just making my filament holder finally.

It does appear the same arm has been used, and the new notches are in the rib, but is that a square location peg I see on the right of the rib?

If so it must have a matching hole in the arm?

I would not wish to sell one of these arms for a mk2 as it likely will not fit, BUT if the DXF files are out, I can easily get them priced up for laser cutting as before IF the demand is there?

Ok I found one change - on the small x-arm there are now three additional cutouts. Is it possible to have these also cut from the existing pieces? Maybe Ian will weigh in with any additional changes tomorrow... Not sure what square you see, the main ribs seem identical to me. new on right.

Just a quick bump...

If anyone is thinking of replacing their acrylic x-arm on the mk1 ormerod, I have three kits left.

These will be the last ones for this model.

I could possibly do a small discount to get them off the shelf.

Thanks

Hi Dave

Any chance of you having more of the Mk1 X-plates made?

Also any idea what shipping to South Africa would come to?

I started building Ormerod's locally, (key word is started) but got stuck with the laser cutting....this to get the price down for the local youngsters.
I had tried to have these cut this side, but seems the guys down here get the dimensions from the DXF files all wrong.

Thanks
Madmob

Hi

Sorry but this part of the project has now come to an end I think, demand had dropped very rapidly due to the release of the mk2 machine probably. I can't get more made unless I could get prepaid orders for at least 15 units.

My apologies for not being able to help.

Dave

If/when DaveK makes a version of the X-arm kit for the Ormerod 2 then I imagine you could use that on your Ormerod 1. You might have to reprint one or two parts, e.g. the extruder body.

I'm still working on my Ormerod2, but the X-arms are basically the same. The small cutouts on the new arm allow the extruder tab to lock into the arm. So the old Ormerod1 kit won't even notice the new cutouts as they are lower than the extruder tab. My extruder has been solid and has no need to be more secure.

I am getting more wear on my Z rod than I would like. Already replaced it twice and now I have a normal height brass nut on it and can already see brass left behind on the screw threads. Not sure if the added weight of the metal arms is part of the problem. I am looking for a local shop to get a set cut and anodized blue or red!

I would guess that the Ormerod 2 X plate also lacks the lips on one side of the cutouts at the top for extruder drives, so that the extruders just drop into place.

I presume you lubricate the threaded rod?
