This error pops up on my Ormerod 2 web interface when printing something sliced with Slic3r. I've been mostly ignoring this error , but it is fairly frustrating and today I got a bee in my bonnet to investigate the cause. I see that M204 is supposed to be to set the default acceleration and I have a feeling it's got something to do with retraction speeds. The XXXX value changes between 1000 andby VortyZA - Ormerod
Some challenges in the upgrade process so far: The cable lengths are not the same because of the new position of the Y motor and end stop. I'm not convinced yet that the ribbon cable arrangement will work with the new bed design. The Power supply and electronics should ideally be on the Y max side like the Ormerod 2, but it's a little tricky to do and I haven't found any mount designs - I'll haveby VortyZA - Ormerod
I've got two Ormerod machines, and I'm wanting to upgrade my Ormerod 1 to 2, however there are a couple of tweaks I'd like to make in the process. The problem is that the Solid Works design files for the Ormerod 2 seem to be incomplete on the github. It's also missing some things like the X axis dxf files and the standard nozzle mount (only has the quickset). The Ormerod 1 had an "Ormerod" assembby VortyZA - Ormerod
QuoteDarathy Dont think its a mirror ,the distance betweetn rods is slightly different i think. It's not unfortunately a mirror. The Ormerod 1 is 80mm horizontally, 12 vertically between the centers of the rods, while the Ormerod 2 is 78mm horizontally (measured from the DXF files)by VortyZA - Ormerod
Quotedmould QuoteVortyZAIf the twist is on the motor side, you would need to remove the motor and belt to get to the screws. It doesn't matter which side the misalignment is, it can always be corrected by twisting the non-motor side only. The goal is to get the Y rods exactly parallel, you can then raise or lower the front of the bed to get it level. Dave I agree, it was poorly worded - the tby VortyZA - Ormerod
I designed a small piece that clips on to the Y axis rods from underneath and reaches down to the bottom of the printer. I printed 2 of them on high quality, then compared them to ensure they were identical. I made sure the board under the printer was flat and not warped itself then clipped the pieces on either side of the axis. I could then clearly see the axis twist. I loosened the two large scby VortyZA - Ormerod
I'll have to take a look for you Treito. My belief is that some filaments are wound tightly on the spool and when they are under strain because they've been straightened or bent in a different direction for too long they will break. The problem is that the closer you get to the middle of the spool the tighter the curve must be for it to be 'relaxed', so there's no ideal curve The reason I haveby VortyZA - Ormerod
I've got some filaments that become horribly brittle if left too long outside of the zip-lock bag. One reel of filament literally spits little pieces of plastic out the back of the printer if I unload it after it's been exposed over a weekend! I'll see if I can get a photo of it - quite something to watch!by VortyZA - Ormerod
Quotedmould Note that the hotend stays down by gravity and is supposed to be able to rock so that it is free to lift up and ride over the inevitable bumps in a print. If you make the hotend solid the nozzle will catch the print at frequent intervals and cause the X or Y axis to slip, or will knock the print off the plate. Dave I agree that is the intention, but my experience is that a lot of tby VortyZA - Ormerod
I tried to print an item from the SD card, but whenever I went to browse for the file I would get "an AJAX error has occurred" which would reset the connection. I really needed to print the file, so I used gcodes to print the file directly. The print went perfectly, but the web interface did not work at at all - kept on throwing up JSON errors. I turned on the developer view in Firefox and capturby VortyZA - Ormerod
It looks to be made from the same material that is used on the plates at the back of PCs where the connectors from the motherboard go.by VortyZA - Ormerod
It looks like your z0 height is too low - there are a few step by steps on this forum on how to check that, so I won't repeat the whole exercise here, suffice it to say that at z0 the nozzle should very lightly grip a standard piece of paper. There might be an over extrusion problem too. Basically what happens is that the plastic can't extrude because it's pushed against the plate, so the pressuby VortyZA - Ormerod
Hey DC42, I've been somewhat busy, but recently managed to update the firmware on one of the printers to this latest version. Since then I have had no "Enter your password" or disconnects happening, so I'm thrilled! Thanks for your hard work as usual! I'd extend the same offer as Planar - if you happen to visit JHB South Africa I'd be happy to buy you a couple of beers or whatever your prefereby VortyZA - Ormerod
I've got one roll of filament that I've found will break if left for 4 days or so. It will break inside the ptfe tube that feeds the extruder, and at the entry into the extruder - basically anywhere it's under a little stress.by VortyZA - Ormerod
The problem that I've experienced with the Prusa i3 setup is the Polulu stepper driver chips - I've had a few of them fail on me and the symptoms are as you describe. It's a fairly cheap replacement, but an annoyance.by VortyZA - Ormerod
I have significantly more wobble in my prints on my Prusa i3 - I think that the Ormerod's Bowden system decreases that because of the lack of hot end weight - it's not trying to decelerate or accelerate the additional weight of a motor.by VortyZA - Ormerod
Hmmm... I bought another Ormerod for the company just before year end. I would have probably not done that had I any indication that there would be no backup a month later.by VortyZA - Ormerod
Quotebrlowe @VortyZA "I use my I3 primarily for ABS, Nylon and Polycarbonate printing because I have an all metal hot end - the Ormerod can do ABS (with some very essential part reprinting), but not the higher temperature stuff." What needs to be done to the ormerod 2 to let you print with the higher temp stuff? and what does that mean? And what parts need to be reprinted before doing ABS? Thanby VortyZA - Ormerod
Quotedc42 VortyZA, please install the special firmware build at . When a password mismatch occurs, it returns the received password and the expected password in the json response. I've downloaded it and will get back to you.. I thought it might be more about the IP that is stored in the list of authenticated IPs rather than the actual password itself.by VortyZA - Ormerod
I have an Ormerod 1 & 2 and a Prusa I3, so this is from my experience: I think the Ormerod 2 is a better out of the box printer - the Prusa i3 kits that I've seen are all RAMPS boards with pololu stepper driver chips of which I've managed to blow quite a few! The electronics are a little underpowered in comparison, and you really need to get the LCD board with the dial - that's essential -by VortyZA - Ormerod
Quotedc42 Sounds like I need to do a special build to provide more information on the meaning of the "err:1" response. I had a glance at the code and it looks like all I need to do is clear the default password in the config and it would bypass that particular problem.. Might be hiding a deeper issue though.by VortyZA - Ormerod
Quotedmould Quotedc42 Did you notice the details of the Ajax error message? I have just fixed a probable bug that I believe was causing the Ajax errors during printing reported by one user. See . No - but I suspect that is a red herring as it seems very random and there is not always an Ajax error when it disconnects, just an unresponsive browser. Random disconnects have been an issue for me siby VortyZA - Ormerod
Quotedc42 Quotedmould There is definitely one of those difficult-to-diagnose bugs in the web interface and/or network code. Most times the web interface is perfect, but every now and again it will disconnect, seemingly at random, sometimes with an Ajax error reported, sometimes not. Thereafter I cannot reconnect to the printer unless I either power-cycle the printer or use a different browser tby VortyZA - Ormerod
Quotedc42 Strange, the password handling hasn't changed in several firmware versions. Which version of firmware were you using previously? Do you have a M551 command in config.g to set the password? I'm not sure it's actually the password handling, unless err: 1 leads you to believe that? I have indeed got the default M551 message in my config with the default password. I have experienced thisby VortyZA - Ormerod
Using your firmware at the office on 2 different Ormerod printers, and both exhibit the same issues on occasion. Basically it will not allow me to do anything using the web interface, because it wants me to enter the password for the printer. Using the default password in the configuration doesn't work, and if you examine at a lower level the web page requests page rr_connect?password=reprap andby VortyZA - Ormerod
This is a fairly common rule-of-thumb that you find on the internet - especially regarding ABS due to it's contraction when cooling. I have found that delamination or weak walls tends to occur above this ratio.by VortyZA - Ormerod
You also need to keep the layer height to a maximum of 60% of the nozzle width, so 0.18mm - otherwise your layer adhesion suffers.by VortyZA - Ormerod
