Quoteiamburny @dc42 - Yep I will be able to modify that part to have a straight slot for the right side of the bed rib, I'll get onto it later. I have removed the belt twist on my Y axis , the belt tension was easily applied and I've done a few prints now with no discernible difference in print quality, i'll still modify the right side part however just to give that as an alternative. Hi Matt,by dc42 - Ormerod
I print this at half size as a general check. It's no good for calibration, but it's quite a good test of bed adhesion (because the contact area is quite small) and the quality of overhangs and bridging.by dc42 - Ormerod
Yes, the loaded gcode file will override the Pronterface setting. Also the gcode file may command one temperature for the first layer and then reduce it to a lower temperature for subsequent layers. The current Ormerod firmware considers the head and/or bed to be up to temperature if it is within 5C of the commanded temperature. To test it, don't print a gcode file, just command the temperatureby dc42 - Ormerod
Unless you have the Kingston SDHC card supplied with very recent kits, the best thing to do with the one supplied is throw it in the bin, and buy a better one. The sort of problem you report is extremely common when you use the SD card supplied. EDIT: Sorry, I didn't read your post fully. Seeing smoke from the SD card is a very bad sign, and I haven't heard of it before. It sounds to me that youby dc42 - Ormerod
Sorry, I misunderstood. Are you commanding the temperature to 200C directly in Pronterface, or are you printing a gcode file that you only think sets the temperature to 200C? If you are commanding it in Pronterface, then I suggest you check the 6-pin connector at the hot end for poor connections (either poor pin/socket connections or poor crimp connections). Mine can get up to more than 300C, altby dc42 - Ormerod
I've had good prints both with the filament supplied with the kit and with PLA from .by dc42 - Ormerod
You can't build the firmware in Arduino IDE, you have to use Eclipse. See this thread .by dc42 - Ormerod
QuotePaulHam I get blobs alot, especially when printing cylinders. Each time the z axis moves up it seems like the extruded starts and the nozzle moves a fraction of a second after, leaving a blob Which version of slic3r? Do you have "Retract on layer change" checked? (I do).by dc42 - Ormerod
I often get a few large blobs on the skirt, otherwise almost no blobs at all. The few that I do get are very small and mostly associated with overhangs. I'm using 4mm retraction.by dc42 - Ormerod
1. How have you measured the temperature? The thermistor is embedded within the heater block, so it is likely to be at a temperature very close to the temperature of the block. If you put e.g. a thermocouple on the surface of the block, it is going to be difficult to get it up to the same temperature as the block unless you clamp it securely in place and put insulation around it. 2. What versionby dc42 - Ormerod
It might be worth adjusting the extruder temperature for layers other than the first. I use 195 for the first layer and 190 after that, instead of the 180 that Squags uses.by dc42 - Ormerod
I don't see any problem with using a standard brass nut, except that it will probably wear faster than a longer one would.by dc42 - Ormerod
Two things you need to check: 1. Choose a suitable IP address for the printer and set it in config.g. See . 2. Preferably, connect the Ormerod direct to your router, initially at least. If instead you want to connect it to a computer that is wireless connected to your router, then bridge the wired and wireless Ethernet connections on your computer,by dc42 - Ormerod
I think your printer may be under-extruding. Check the filament extrusion rate calibration (described in the Commissioning instructions). Also measure the filament you are using, at several places, and put that value in the slic3r settings. If those are already correct, try increasing the extrusion multiplier in the slic3r filament settingsby dc42 - Ormerod
Thanks, Matt! Bob: can you use Wireshark to trace the initial connection between the client and the Ormerod, under both Ubuntu and Windows? Maybe there is some negotiation going on that causes Ubuntu to use short packets.by dc42 - Ormerod
Hi Dan, The 0.54 firmware is quite old now. I suggest you use either the 0.57a firmware from the RRP master branch, or my own 0.57g or 0.57h firmware and Matt's new web interface. See for details. Note there appears to be an issue with using Ubuntu linux with my firmware and web interface at present, which can be worked around if you are running a local web server.by dc42 - Ormerod
John, that looks good when I view it in slic3r except that the extra tab on the left hand side looks too high. It needs to be 7mm lower than the rest to provide room for the IR sensor head, and slic3r says the total height is 21.61mm. Can you confirm that the height of that new tab is about 14.6mm?by dc42 - Ormerod
Check the current rating of the 12V supply on your other ATX power supplies. You need a rating of at least 20A, and a higher rating (e.g. 32A for the Alpine and the Corsair) will hold the 12V supply up better under load.by dc42 - Ormerod
Hi Matt, I've come across an issue with the latest web interface. When I press STOP in the middle of a direct print (because the print has gone wrong), then reset the printer, then press the Connect button, it continues the print. This is most undesirable, especially as the axes are no longer homed. STOP should cancel any direct print that is in progress. I'm also having trouble getting the setby dc42 - Ormerod
There have been a few reports of the power supply shutting down, and RRP were investigating. Ask RRP for a replacement under warranty. With any luck they will send you an Alpine (the other brand they have been supplying), which has a higher current rating on the 12V supply. It is normal for the fan to slow down a little when the bed heater comes on. I am currently using a Corsair CX430M insteadby dc42 - Ormerod
John, thanks very much for your help so far. I have printed the new heatsink duct and installed it, with the sensor on it. It's working, but could do with a few tweaks if you have time. With the duct lying on its base as printed, so the new slot for the thermistor wire is at the bottom and facing you: - Shift the new piece (including the holes) right 0.5mm - Shave 0.5mm off the bottom of the newby dc42 - Ormerod
I took some measurements using 3mm glass, then switched to 4mm and remeasured. Using 3mm glass, the centre of the bed was 0.175mm higher than the average of the corners. Using 4mm glass, the centre is 0.075mm higher than the average of the corners. This is a useful improvement. I used the same 9mm photo frame clips, so the clamping force will be a little higher using 4mm glass. I currently haveby dc42 - Ormerod
Frank, I suggest you truncate the .g file a few dozen lines after that line, then it will be small enough to attach to a post. What firmware version are you using?by dc42 - Ormerod
Hi Frank, would you like to try 57g from too?by dc42 - Ormerod
Hi Paul, I've completed a short print and an 8h30min print using the new interface and 57h. However, you might want to try the previous version (57g) which is available at . There was some sort of memory issue in 57f which I haven't yet tracked down, and 57g was my initial (successful) attempt at reverting some buffer sizes to avoid that issue. Compared to 57g, 57h increases one of the buffer siby dc42 - Ormerod
What exactly is the gcode that is setting Z to 0.30? Is it by any chance setting X and Y in the same gcode? The current firmware doesn't handle combined XYZ or XZ or YZ moves properly.by dc42 - Ormerod
I found this in the Ubuntu manpages: >> By default, Linux UDP does path MTU (Maximum Transmission Unit) discovery. This means the kernel will keep track of the MTU to a specific target IP address and return EMSGSIZE when a UDP packet write exceeds it. When this happens, the application should decrease the packet size. Path MTU discovery canby dc42 - Ormerod
Thanks for your kind comments on my bed support. It isn't bent, except slightly at one corner where I cut it without adequate support for the piece that was about to fall off. The 6 drilled holes need to be in exactly the right place, but the position of most of the rectangular cutouts is not critical. I cut them roughly with the jigsaw (or drilled holes and then joined them with the jigsaw) andby dc42 - Ormerod
Very strange. Two suggestions: 1. Have you eliminated power supply issues? The 3.3V regulator on the Duet board is very marginal when the Duet is powered only from the USB port. I don't know what sort of a mac you are using, but especially if it is a laptop, the USB power could be marginal. 2. Do you have a friend with a Linux or Windows computer who could try programming the Duet?by dc42 - Ormerod
That sounds very plausible. Maybe it's the MTU size that is too small. If you run ifconfig, what MTU size does it report?by dc42 - Ormerod
