Cheers for the links. I'd reverse engineered the latest ormerod 2 x-carriage/bearing & belt clamp from the RepRapPro github and it has been very awkward to work with, particularly with the bearing running along the base ofthe x arm and its nut hidden. I'll have a look at them before a redesign.by WesBrooks - Ormerod
The certificates and unique numberings for the kits seemed to finish before the start of the Omerod 2s. Had an early revision 1 version 2 in 2014 and a new old stock kit that was re imported back from Australia and neither had them.by WesBrooks - Ormerod
I'll check out the current setting again, but thought it was at the limits of the Ormerod motors. This was at 0.3mm layers. I'd recently considered dropping nozzle temp as the y-axis bearing mount with the tag was showing significant over melting on the tag. This was with 3 other tags building at the same time and a radial blower at 100%by WesBrooks - General
Evening, A delay response but getting there eventually! I've been focusing on trying to get a routine for dialling in the processing parameters as effectively as possible and as per usual plastic has proven itself again and again to be a weird material, and far from linear in terms of both resistancve to flow and change in properties with temperature, sometimes a few degress can change the charby WesBrooks - Ormerod
I tend to see missed steps on my 12V geared RepRapPro extruder/hotend at about 10mm3/sec through a 0.4mm nozzle. That's around 65-75mm/sec print speed with PLA @190C, 0.3mm layers and 0.5mm extrusion width. Not that greater speed.by WesBrooks - General
Finally got back around to tweaking the cad and went for the following. Spring fowls the cap heads but not that much on an issue. Ignore the printed coupler, that was a stop gap I haven't changed back out yet.by WesBrooks - General
When defining the probe you can tell it to probe multiple times until a specific threshold is reached. Not used the dc42 probe yet, it is supposed to be far more tollerant to changing external factors than the stamdard RepRapPro IR semdr which is fussy with sunlight, halogen desk lights, and incandescent bulbs -or shadows. Watch the probe value on the web control and wiggle the wire a little aby WesBrooks - Duet
Hi, Currenly building my first of two P3Steel printers. One to allow me to experience Merlin/RAMPs (been spoilt with 32bit controllers to date) and a second to convert a Mendel into something considerably easier to maintain. I'm building this machine from scattered Spanish manuals with no other tongue than english which has resulted in a few rookie level errors such as bed 180 degrees out aboutby WesBrooks - Prusa i3 and variants
I've a couple of Ormerods with the standard reprappro extruders that have no spring loading or adjustment. These are geard but tend to get back driven by the filament when I try to get data points for non-linear extrusion correction at the higher speed points. The system seems limited to about 10mm3/sec at 190C for PLA. Is this all down to the hot end design or due to lack of extruder torque? I'mby WesBrooks - General
Used Bondtech bmg after getting thoroughly frustrated by the under powered and unreliable unit from a competitor. The BMG is geared, but nit with the gearbox you see on the earlier models. The difference between the BMG and the more traditional design of the previous competitors unit (hobbed shaft forcing filament onto plane undriven roller) was clear. A lattce like structure failled each attemptby WesBrooks - General
Sorry, meant direct interms of not geared, rather than direct to hot end. So forgetting age and focusing purely on performance for bowden extruders are the wades still holding their corner?by WesBrooks - General
Just recieved a kit where the Wade extruder has been replaced by a direct extruder. Are the benefits of this mainly for the supplier rather thn the user? ie lower part count, less to print for the kits? I've always been wary of direct extruders due to the lower torque.by WesBrooks - General
Yeah, my solution isn't ideal but was enough to get 45 degree overhangs, bridges, and a middling effort on the benchy (will reply to your other post later!) working on a more-or-less stock system without causing too much headache or obstruction of hot end fan vents. Pleased with tje bridging now.by WesBrooks - Ormerod
My pictures above and attached files show a standard print head with my radial fan mount.by WesBrooks - Ormerod
I'm putting off printing a new extruder for the time being as I would like to have a more detailed look at the belt extruder designs. However, that maybe forced on me early if this clip doesn't hold. If so I'll be looking for something very standard, just with a boss for a bowden connector with PTFE guide if needed. There are herringbone gears (constant contact and no axial force that you wouldby WesBrooks - Ormerod
Hi All, Probably quite obvious to those who have been on here a while and as I type it is seems obvious to me too... However, in the ever going effort to improve print quality I noticed that my bowden clip (on extruder) was waving more than royalty. Fixing this appears to have made a step change in part quality. There are many options for fatter clips or extruder designs with bowden connectorsby WesBrooks - Ormerod
Looks like the maximum recomended temperature for the PCB het neds is aboit 120C. Realistically this means you can't raise that any further safely.by WesBrooks - Ormerod
Good to hear it's running. Check for M143 in the config file. Alternately run M143 H0 in the console to see what the limit is currently set toby WesBrooks - Ormerod
Quotethe_digital_dentist Infill can be thicker than outer perimeters if you use Slic3r. For example, slice in 100 um layers and in the infill section, under "Reduce printing time" select "combine infill every" and set it to 3 layers. You'll get 100 um perimeters and 300 um infill (assuming you have an appropriate sized nozzle in the extruder). Cura can probably do this, too. Thanks, I'll haveby WesBrooks - Printing
For a specific machine type maybe. Cartesians like rectalinear, perhaps the others work best with other machine designs.by WesBrooks - Printing
QuoteMKSA Gee, so many infill choices, parameters ... so I used to select honeycomb. Now I discover most are useless gimmicks. They don't make 'em like the used to do they? All this fancy GUI, only need a terminal! ;-) To be fair I stick with rectilinear myself but did come away wishing the infill could be 0.3mm layers and the perimeter on 0.1. May well be a possibility but the couple of parameby WesBrooks - Printing
One issue with belt driven z-axis is it drops on power cut or machine shut down. Ideally you' used braked steppers with the brake releasing with the associated stepper drive enable signal. If left to drop the back voltage geenerated by the steppers could cause issues.by WesBrooks - General
I've built an open rail based core xy before thanks. I'm familiar with them but saving the core xy project for later.by WesBrooks - General
@NinthDimension Sorry my bad. I was referring to the product family as v-slot rather than using the v-slot as a rail. The original company has gone, but RepRapLtd exist and they ship the Fisher Delta printer. They do keep en eye on the forums and still offer parts for the printer kits that were discontinued with RepRapPro. There's a piece on the closure of that company in the Ormerod section of tby WesBrooks - General
That is toasty! Which material needs that heat - or is it more with the heat the part is better rather than 'need'? Heard that PC wasn't really happy until the bed temperature exceeded 135C.by WesBrooks - General
Standard nozzle position looks to be about 5mm from the x carriage, This would put the whole system about 18mm further from the x-arm than standard. With a bit of a re-think (after the system has proven itself!) I think I should be able to get that below 15mm. The whole working area could be recoverable if desperate by moving the IR sensor -y a little (and changing the trigger) and shifting the zby WesBrooks - Ormerod
Thank for your reply. Loads there! I thought the same regarding belts and ende up with parts about 1.5% undersize. The RepRapPro kits ran on MXL belts. These are imperial and by eye unless you count 50 or 100 teeth look very similar to GT2. The pitch is about 2.03mm! With regards the chamber temp it'll probably hit 40C with passive heating alone. Decent insulation and it won't take much heatingby WesBrooks - General
Hello Sally, good to know but apologies in this instance as I had a couple of unneeded ones that I've sent his way. Can't rule out damage in transit but hopefully he should be sorted. I however may email about some PSU / Duet mount parts!by WesBrooks - Ormerod
Out of the house now but the nozzle centre line is about 23mm from the surface if bolts to on the x carriage. Not sure what the standard offset is. Offset in the x axis direction relative to the probe is the same.by WesBrooks - Ormerod
Just noticed my new fans are 0.25A rather than 0.15. Should shit some more air! :-) Edit: *smugmode* :-) That whole assembly should fit on a standard Ormerod 2. Not bolted on the machine yet and thinking about some heat reflective tape close to the heater block. Edit 2: You do loose some y axis travel.by WesBrooks - Ormerod
