Don't mean to sound daft or noobish - been printing for a while now, but.. Explain white tape and the x-homing tab?by VortyZA - Ormerod
Some pics would help us to understand exactly what you're saying, but sticking to the bed is a fairly standard problem if the bed isn't heating or the glass isn't clean, or the head is too high (z-axis) off the bed. If your IR sensor is working fine, there's a section on the RepRapPro website that talks about commissioning the z-axis and calibrating the sensor. You should also calibrate the bed (by VortyZA - Ormerod
I had the same problem, but RepRap replaced by fan under warrantee.by VortyZA - Ormerod
I actually still have the same grinding problem with the x-axis. Added a limit switch (the original kit didn't have one) which mostly fixed it, but if the x axis is already at 0 then it just makes a horrible grinding noise when you home it. If I moved X in a positive direction, then homed X it would mostly work. The grinding does stop after it believes it's moved 200 after which it believes thatby VortyZA - Ormerod
It's a fairly common problem however I would have thought that the github config files should have been ammended to remove that? All the best for tomorrow.by VortyZA - Ormerod
Quotedmould QuoteVortyZA Someone mentioned being able to recover a print that failed for some reason. I can't find the message though. Is there a file or something that keeps track of where in the gcode the printer was when the power cycled or whatever? You may be thinking of someone who was also asking whether there is any way to recover a print by rewinding to a particular line. I do not beliby VortyZA - Ormerod
Sounds like your initialisation string is telling the Ormerod to use absolute coordinates instead of relative for the extruder. That causes the Extruder to essentially 'rewind' after a long line. Look in your initialisation string in Slicer or whatever - I believe it should be a M83 for Relative E instead of M82 for Absolute E.by VortyZA - Ormerod

Did the support come off easily enough and cleanly ezwul? It looks OK from the picturesby VortyZA - Ormerod
I've added versions of the PTFE and normal with breakaway support. You should be able to print without any support now. Probably should have done that in the beginning but I'm fairly used to Kisslicer's support just working!by VortyZA - Ormerod
I'd like to see some of your solutions - perhaps I can make a permanent change that suits?by VortyZA - Ormerod
If I'm designing things that I want to print without the use of supporting material, then I'll make sure that overhangs don't exceed 45 degrees from vertical. Much more than that and the material will either droop or be dragged around by the head a little! So a curve like the one you show there would start with a 45 degree, then curve nicely towards the top. Occasionally I'll have to use supportby VortyZA - Ormerod
Quotedmould QuoteVortyZA One of the things I like the most about dual extruders is the ability to print all complicated support with the water soluble PVA - that wouldn't obviously work with a single nozzle. I don't see why not. You would need a sacrificial column somewhere where a few mm can be extruded after changing material on each layer to clear the hotend of the previous material. If theby VortyZA - Ormerod
I had a freeze when my laptop's battery went flat and died. It took the print with it!by VortyZA - Ormerod
Are you printing with support? And what temperatures do you extrude at?by VortyZA - Ormerod
One of the things I like the most about dual extruders is the ability to print all complicated support with the water soluble PVA - that wouldn't obviously work with a single nozzle. I've seen videos of a 3 extruder setup with a single nozzle, and it looks very interesting, but what is worth noting is that the colors don't *mix* per se, but rather come out like some brands of toothpaste! This gby VortyZA - Ormerod
I use Kisslicer to slice, and I set a 1mm gap between support and object, if it does print support in the hole a piece of filament pushed down the hole removes the support fairly easily. It would be nice to have the ability in slicers to preview the support and remove the ones you believe don't need..by VortyZA - Ormerod
This seems like an odd suggestion, but it's something I found - ensure that your glass is held firmly in place, because the friction when the hotend moves dragging plastic can be enough to move the glass slightly, causing strange layer shifts that can be difficult to identify because they are not always constant.by VortyZA - Ormerod
Some things I've learnt from printing ABS: ABS seems to absorb a lot of moisture from the air - keep it in a sealed bag with desiccant. Printing with ABS that has been left out for a while causes bubbles in the print (you can actually hear them popping sometimes). The terms change between slicer programs, but print with a raft or a grid between the object and the plate with a wide brim. This platby VortyZA - Ormerod
Has there been an upgraded X-idler tensioner for the belt that I missed? I find that a) the belt is very difficult to insert nicely, and b) the tensioning was difficult - not much movement on the motor it difficult to keep tension up while tightening the screws. I would have thought that the end of the cross arm could just have a tensioning screw like the way you tension the Prusa i3.by VortyZA - Ormerod
Looks like a belt is loose, but I'm sure you've checked that already.by VortyZA - Printing
I'll take a look when I get a chance. Wasn't there a nice clip replacement someone designed - hooks both in the hole and above?by VortyZA - Ormerod
I've got a problem whereby I have run the RAMPS1.4_TestCode.pde with a standalone motor and every axis behaves as expected except for the Z axis which does absolutely nothing. I moved the driver from the Z to Extruder1 and it worked fine there, so I'd say that the driver is OK. I checked the RAMPS board for dryjoints and solder bridges and didn't see any - What more can I look for?by VortyZA - Reprappers
Quoteormerod168 Quotedroftarts...The only problem I can see is that variable diameters of plastic cause different meshing of the gears. It would be better if just the idler was sprung, as in other extruder designs...
