The machine is alive and all heaters tuned. Delays from over extrusion on my work horse Ormerod and trying to get decent parts off a Mendel with a big heavy diamond 3-1 hot end on it. Not much progress on my to-dos list but have sorted the z-lower mount and am currently printing first attempt of a radial fan mount (more fit check than expecting right first time) that has two long slots eitherby WesBrooks - Ormerod
Hello, I've been thinking about moving up through the materials in terms of temperature capability from PLA to PETG and onto Nylon with PC being an ultimate goal. I've got another thread in the printing section of this forum trying to attain ball park figures for processing temperatures and this thread is to collect a few ideas on how I may adapt the Ormerod design to increase its ability to copby WesBrooks - General
Material suppliers naturally tend towards presenting running their materials as stress free as possible, and so I'm unlikely to read on their blurb: "Won't print extrusion brackets with 5mm sectons for love or money!". With that in mind I'd still welcome stories ftom the coal face.by WesBrooks - Printing
Ok, from preliminary look around the following eems a reasonable guide. Nylon 250C Hot end 90C Bed Enclosure Recommended. PC 300C Hot end 135C Bed Enclosure essential. It's looking like nylon is do-able without a major think on the machine so long as it has an all metal hotend. PC would require a new bed heater and a serious think about the machine to ensure all parts are fine upto 60ish ambby WesBrooks - Printing
I think the standard infill is using bridging parameters and so bridge flow has an effect. I found it was a pain to get infill good at layer thicknesses lower than 0.3mm for a 0.5mm nozzle. Petimeters and non bridging infill worked fine at 0.1mm. As others have suggested swapping to in infill style that avoids bridging will help. Prusa edition not essential for that.by WesBrooks - Printing
Hi all, Anyone working with these materials? What are your favorite bed and chamber temps? Will be looking at material supplier data too, just hoped there may be others working on the coal face! Thanks.by WesBrooks - Printing
If your UK based then I've a couple here I could get in a jiffy bag and over to you for the price of said jiffy bag and postage. Further afield may not be so cheap. Edit: Your previous posts show you are (or were!) UK based. Just PM me your address and I' get them in the post for you around lunch time. Jiffy bag and first class should easily be less than £10, most likely less than £5. If so I'llby WesBrooks - Ormerod
Are you from the UK? Edit: First try would be contact RepRapLtd and see if they can get some for you. If that fails let the forum know where you are and someone may be able to print a couple for you. May not be as good as cut acrylic but should get you buy until you have a better solution.by WesBrooks - Ormerod
Have you got a spare printer? I've printed some for my prototype and they are holding up ok.by WesBrooks - Ormerod
Bugger. Asked for opinions on the Duet forum on P3Steel machines (generically rather than Orballoprinting) and didn't think to search this one. I'll pre-print some spare parts while I wait for the printer to be dispatched! How was the printer once you resolved the printed parts issue? With regards the printed parts the website currently states a 65% fill density, which is far greater than pictby WesBrooks - General
Cantilever elevators can work. That one looks like a spring board. Have a look at the core xy systems if that one has interested you. Less moving mass, both motors controling the x & y axis are stationery.by WesBrooks - Ormerod
QuoteMKSA Improper use/mount of any component will lead them to fail. Don't blame the component (except some crappy chinese that are bad fro the start of course) My point was it didn't take sliding well. The delrin antibacklash block will always be subjected to sliding. It was only jammed for a build.by WesBrooks - General
Had flatspots on my Delrin V-Slot wheels on a build for a previous employer. Granted the wheels - in error - were too tight against the rail, but the ease at which the aluminium extrusion wore a flat in the wheel in its extrusion direction doesn't give me confidence in its durability.by WesBrooks - General
Thanks for your feedback. My current z-nut-trap part has the lower, smaller part constrained a bit too tightly around its circumference by long bolts constraining the top part. I'll redesign to use much shorter bolts and ensure the only constraint on the sprung loaded tail is the tags that engage on the main nut.by WesBrooks - General
Just printed a motor coupler this morning but haven't had a chance to fire up the machine yet. I'll do a coupke of bench mark tests with the original sensor then swap over. I've started pondering the v-slot based x-arm. I'll make sure it can swap to open rail if needed.by WesBrooks - Ormerod
On my recent look through the machines and shops it's become apparent that the ball bearing style bearing has fallen out of favour and dry maintenance free bearings are more popular. Igus Drylin I think it was called. Not sure if that is your issue but I think the bearings do run in a loop. One thing to be said for your deviation is it's a nice looking sine wave! I wonder if the wavelength is cloby WesBrooks - Ormerod
Perhaps it's the wiring but that's going to be tricky to resolve. How free to rotate about the x-axis smooth rod is your carriage? Perhaps we need more preload to stop minor loads moving the head?by WesBrooks - Ormerod
Quotedc42 My Ormerod is currently decommissioned due to lack of bench space, but I'll try to extract a height map from the SD card and post it tomorrow. Fair enough, approaching a similar problem myself. Thanks all the same, it'll be great to see what we can reasonably expect from the modulated sensor. Aluminium bed support or mdf on yours? Ormerod 1 or 2!by WesBrooks - Ormerod
Unfortunately a well known 3D Printing part supplier thinks it is fair play to offer next day delivery on orders placed in good time on a Thusrday amd not deliver until a Monday. I'll be having a real close look at this when I get the coupler.by WesBrooks - Ormerod
I'm wondering if this is due to the cabling or filament. The latter is of course far easier to test for! dc42 - What does the mesh look like on your Ormerod?by WesBrooks - Ormerod
Cheers for the bed.g mod that makes sense thanks.by WesBrooks - Ormerod

Quotedc42 That pattern indicates that there is a problem with your X axis. At low X values, the trigger height is depending on the direction in which the X axis last moved. Assume you've got your Ormerod pretty tightly tuned in? Mind giving us a screen shot of a gold standard for our machines and your sensor?by WesBrooks - Ormerod
I ordered mine from RepRapWorld when I was looking for a supplier of 3DLac. I've since found 3D Filaprint stock it and I strongly suspect it's just branded hairspray! I've just ordered a few from E3D and they look to be the same dimensions:by WesBrooks - Ormerod
That's fair enough. Don't get me wrong, the dark side is tempting! :-D Well worth a poke once you've got a steady base to work from. Trouble with these systems is that by their very nature there are so many things that come into play it can be very difficult to know what is causing problems until you've played around for a bit. With regards your tests I would be more interested in the deviationby WesBrooks - Ormerod
Quotedc42 Detecting the surface is very easy for the differential IR sensor that I make. But as you say, the reflection from the back surface of the glass interferes with the reflection from the front surface, causing a change in trigger height. This is manageable under some conditions. My Ormerod uses 3mm float glass and the aluminium bed plate is painted matt black. I get acceptable results froby WesBrooks - Ormerod
If you want to do your own thing that's fine but we will be unlikely to help you out of difficulties. If you want us to help out any further with the stock set up then I think you need to do the following including bits CheeseAndHam has already suggested: Update to the latest version of firmware and web control software.Find a way of securing four 25mm paper targets (or perhaps masking/paintersby WesBrooks - Ormerod
Morning. A typo led me to RepRapLtd's webpage this morning rather than the forum. Had a look at the fisher delta kit which has a radial fan mounted on the hot end. Next time I look at the duct I'll be having a dig around for those files to see what they are like.by WesBrooks - Ormerod
