You may want to consider taking apart and putting your printer together again if you have no other choice. I also had a self sourced delta, which I had to rebuilt twice before I was able to get it print properly. Alternatively you may first want to check for effector tilt, using a spirit level.by Wiireless - Delta Machines
Did you check the vref values of the stepper drivers or the set screws on the timing pulleys? If one of your steppers are skipping steps, the z-layers would probably not align together properly but since you said you managed to print a nice vase, the problem may lie somewhere else?by Wiireless - Delta Machines
Quotedc42 Roller mechanisms can be accurate enough (I use them), but you need to make sure that the carriages are not rotated about either the Z axis or about their faces. When I rebuilt my delta, I had one too many washers between one of the carriage wheels and the carriage truck, and this caused the carriage to be rotated about the Z axis, which threw the calibration out. Also make sure that inby Wiireless - Delta Machines
Alright thank you DC for the reply. I will try reprinting the roller mechanism with a more accurate printer and try again. Else I may need to look at alternate methods of the linear guide systemby Wiireless - Delta Machines
Quotedc42 The dip may be caused by your adjusting the diagonal rod lengths. Did you calibrated the tower positions first? Yes I did. There was already such an issue when I left the M665 A,B and C values as 0.00 I first levelled the bed, then tweaked the A,B,C values in M665 and then recalibrated the endstops and this is the current result that i ended up with..by Wiireless - Delta Machines
Hi there, I am currently trying to calibrate my custom Kossel but I have ran into some problems with the Z-levelling. My prints all stick well to the bed and are rather levelled at all three towers (X, Y and Z). However, I noticed from printing that the effector dips at the point between the X-Y towers (at the opposite end of the Z tower), causing the filament extruded there to be extremely thin.by Wiireless - Delta Machines
Repetier had been giving me some problems and that was why i swapped back to marlin. May try again. But if it worked once, it should probably not be a firmware issue. However i cant seem to pinpoint where the mechanical fault lies at..by Wiireless - Delta Machines
The correction matrix is automatically applied to your printer and will stay in effect until the next homing. That is why you are able to print flat after running G29 and have to rerun it befor every print. Check the link i posted to save the correction to eeprom. Havent tried it myself though and i think not everyone would recommemd it.by Wiireless - Delta Machines
Someone correct me if im wrong, but running G29 only calls for the printer to generate a correction matrix. It does not permanently save the bed levelling correction, even if you run M500. The moment you home your printer, the correction will be gone and you need to run G29 again before the next print. But i think that it can be done though. Take a look at this. *assuming that you are using rampby Wiireless - Delta Machines
Hi there, I recently managed to get my DIY kossel manually calibrated to print very flatly. Had a few decent prints. However some software bug caused my nozzle to crash straight into to corner of my bed, resulting in the need for recalibration. However i have been unable to get my printer back to its previous state any more. I am using the method of manual calibration of the 3 points in front ofby Wiireless - Delta Machines
Anyone has any idea? BUMPby Wiireless - Delta Machines
Quotenebbian Is the height dependant on the direction you got there? ie. X -> Y is a different height than Y -> X? Or is it just a case of the head being the wrong height when between towers? If the latter, I'd highly recommend going back over your build with a pair of calipers and a set square, and ensure that your towers are parallel and not twisted. Failing that you can always try ouby Wiireless - Delta Machines

Quotesungod3k its part of m666. you can enter them as paramenters Hi, thanks for the reply! Though im quite sure M666 does not have such an option, at least not for my version of marlin (I am using one of the more recent versions of RC-bugfix). M665 has new A,B,C values which I have not come across until recently. Correct me if im wrong but I get the impression that the values of A, B and C areby Wiireless - Firmware - Marlin
Hi guys, I have been trying to use dc42's least squares online delta calculater (http://escher3d.com/pages/wizards/wizarddelta.php) again after rebuilding my delta.

Quotenebbian Funnily enough I've finally gotten around to adding a good autolevel sensor to my printer, and last night was having the same issues as you! It seems as if the code thinks that the sensor is triggered the whole time, despite M119 showing the endstop Z-min open/triggered messages working properly. I'm going to dive into the code soon to see what's going on. Yes, I have the exact saby Wiireless - Delta Machines
Hi guys, I need some help with the configuration of my auto bed leveling in marlin. Somehow, after enabling the autoleveling option in configurations.h, the effecter will move up continuously, despite already triggering the endstops and attempt to move past the endstops. I have not found any other options for this and wqs just wondering if i missed anything. Cheers and thanks in advance for any hby Wiireless - Delta Machines
QuoteBlasphemousBits I personally got nowhere with minows guide. For one thing, there's some stuff in there that seems like it must be realy dated and obsolute. He seriously advises to avoid the EEPROM and instead go through the brain damage of editing configuration.h, recompiling, and re-uploading with each change?!?!! You have to be kidding!! This video on the other hand really helped me outby Wiireless - Delta Machines
Quotedc42 Wiireless, If the problem gets worse with each change then something is clearly wrong. Did you select the correct firmware type in the calculator? Did you enter the correct initial values into the calculator? Are you entering the correct sign of the height error, i.e. positive where the nozzle is too high and negative where it is too low? If you believe you are doing these things corrby Wiireless - Delta Machines
Hi David, okay I will try the calibration process again hopefully tomorrow and will update again. However, I would just like to confirm if what I am doing to adjust the "tower position angle corrections" is correct.

Hey, thanks alot for the reply! I have checked out your calculator although I think that I may be doing something really wrong since the problem is getting worse and worse with each change I make...

Hi there, I have been continuously calibrating my kossel for the past weeks but I cant seem to get my nozzle to move parallel to the printbed in all directions. To be honest, it is getting pretting frustrating The problem here seems a little weird to me.

Hi, thanks for the reply. Yes the steps per mm for all 3 axises are 100 This is an occasional problem that happens more regularly then not. It only started appearing when I tried to print something. Previously when callibration the print bed, there was no such issue and all axis would always home the same way, which is rather weird. Any chance that it could be the motor that is broken?by Wiireless - Delta Machines
Hi there, I am currently building a kossel as my first reprap project. However so far I am having many issues with the stepper motors. One of it is this, whereby when the printer homes, the X and Y axis will move up to the top first before the Y axis and sometimes it would just Jam in the middle. Only by pressing the home button again will the Y-axis move back to its homing position. Here is a viby Wiireless - Delta Machines

Hi, thanks for the reply. The value of LCD_TIMEOUT_TO_STATUS in ultralcd.h is 15000.

Is there any way to test for a faulty LCD controller? Cheers!by Wiireless - RAMPS Electronics

Hi, thanks for the reply! If I choose to stick with 1.8 degree steppers, is a holding torque of 40N.cm enough? I read somewhere that the holding torque only affects the printing speed, whereby more torque leads to higher acceleration and thats all. If so then those should be fine right?by Wiireless - Stepper Motors, Servo Motors, DC Motors
Hi guys, Repraps have recently caught my eye and I have been planning to build one soon. So for now I have been furiously sourcing for parts.
