Once again, thank you, the light has finally gone on. I increased the diameter from 8 to 12 and let it overlap the gear teeth. This seems to have eliminated my problems, another learning experience. This gear is for a very low speed geared 3v DC motor driving a number of gear sets of various sizes in a Tellurion, i can adjust the length of the shaft to center the driving gear on the driven gear.by NAP1947 - Printing
Thank you for your response, I am going to show how little I know here by the following. I am using a 0.4mm nozzle and 1.75mm PLA filament. I do not understand where your math comes from, could you explain that more clearly so that I can make appropriate corrections to my Slic3r setup.by NAP1947 - Printing
I am attempting to build a gear with a shaft on one side, see STL file. The shaft is 10mm high with a 5mm hole in the end, the hole has squared off sides to provide grip on the motor shaft. The print is OK until it reaches the bottom of the column hole at which point it reduces from 8mm to 6.3mm. The Gcode file is also attached as it seems to be the translation from the STL to the Gcode that iby NAP1947 - Printing
Long story short, the operator made a mistake, I replaced the hot end nozzle and did not get it installed properly hence the hot end error that I thought was the mosfet, adjusted hot end and all is working. I still have a very minor convex bed issue, it only affects squares larger than 90mm and only in 3 of the 4 corners. Once past the first layer it prints fine, I estimate I am about .05mm aboveby NAP1947 - Delta Machines
Thank you to everyone that contributed, I have the printer setup and configured. I went through all the mechanicals and found a few things that had worked loosed which I tightened. I also found a discrepancy between the rods ends at the tower and the ones at the effector, these have been adjusted do all are equal. Now I have the printer working the Mosfet for the Hotend has gone bad and will notby NAP1947 - Delta Machines
Hercek, you are right I am confused. However your explanation has helped and I will try and get my head around the Github article over the holidays. The big point I get from your explanation is the rods not only need to equal in length but not overly long. The FLsun spec calls for 218mm rods, mine are 222mm. So if I shorten the rods to 218MM it may reduce some of my error, I will try that afterby NAP1947 - Delta Machines
DLC60, you gave me help with my original thread “ FLSUN Delta (not mini) Setup” when I was trying to make the manual level process work but I was never able to figure it all out and after Mac problems and then somehow managing to destroy the original MKS Gen 1.0 board and replacing with another 8bit MKS Base board I went back to a micro switch to detect nozzle calibration. So at present I am usinby NAP1947 - Delta Machines
Ohmarinus, so I am not alone, perhaps someone can help us find a solution. One thing I forgot to state is that I replaced the original MKS Gen 1 board with a newer MKS Base model, still 8 bit.by NAP1947 - Delta Machines
I started a new post as I have moved on quite a bit from the previous attempt to calibrate using the manual process. Where I am, FLsun Kossel Mini, Bed is 1/4" aluminum plate checked for flatness in a proper machinist lathe, Delta Rods are all 222mm the ends are Traxis type and tight with no play in the connections. The effector plate has been changed to an injection molded type, the print is cby NAP1947 - Delta Machines
I played around with the Z Min and Z Max setting to no avail. Tried a test print from Thingiverse with current settings and the edges of the skirt circle were squished (too thin) and the centre was not adhering. Therefore, I assume my delta has a convex setting to it, and needs the centre pushed down and the sides brought up. The sides I can do with tower endstop adjustment but I need to figure oby NAP1947 - Firmware - Marlin
I played with the Z_PROBE_OFFSET_FROM_EXTRUDER for a while with no results. I then realized this adjustment must be used when a Z Probe device is present, I do not have one on my printer. I did find 2 definitions one for Z_MIN_POS and another for Z_MAX_POS. My MIN is set to 0 but the MAX says MANUAL_Z_HOME_POS. I assume the MAX position is the top of the Delta Towers, which would be 227.6 mm fromby NAP1947 - Firmware - Marlin
I looked up M851 g-code and found the equivalent in the Configuration.h file is “ Z_PROBE_OFFSET_FROM_EXTRUDER”. This is what I have been trying to figure out. Thank you again.by NAP1947 - Firmware - Marlin
Thank you, I will do that. However, I also want to understand how to do this same thing using the coding in Marlin as edited by Arduino.by NAP1947 - Firmware - Marlin
Been a long road but my FLSUN kossel is almost ready to print again. I have everything set using the manual configuration process to modify the Marlin script using Arduino. However, now I have all the tower heights exactly the same the centre height is 0.7 mm above the bed at Z0. I cannot find anything to guide me in this last adjustment that relates to the current Marlin version. Everything I fiby NAP1947 - Firmware - Marlin
Thank you for your response.. I decided to keep it simple and ordered an MKS V1.4 8 bit. I can remain with Marlin firmware as well as the supporting software and not spend a lot on what is really a pretty cheap unit. Cheersby NAP1947 - Smoothie
I have been unable to buy a true smoothieboard so I opted for a BigTreeTech imitation, that is proving to be nothing but frustration and I am going to return it. That leaves me with no controller for my delta (I successfully destroyed my original MKS). Can someone advise a board that is not only available but has good support for novice user?by NAP1947 - Smoothie
Hopefully final update. It took a lot of time but I have the DELTA_RADIUS almost perfect. I am taking a forced break as I succeeded in frying my board, new one is on the way. I want to thank the folks that responded to my request for help, your patience and clarity are greatly appreciated. I have certainly learned a lot. Cheersby NAP1947 - Delta Machines
OK My rookiness is showing again. What I should have said was "If I change the Z0 or the tower end stops the Z0 is always 0.30mm out" If I do a G1 Z0 the nozzle stops at the bed. If I do a Z0 at any of the 3 towers it is always 0.30 above the bed. It is this 0.3mm I am trying to finesse. Does that make more sense?by NAP1947 - Delta Machines
I have rechecked all of the level settings with a square to ensure all the tower to bed angles are 90 degrees. I have adjusted and stiffened the towers so they are all parallel, top and bottom measurements are as follows, X to Y 285mm, Y to Z 285MM, X to Z 283mm. So if I have these correct and my end stops at each tower are adjusted to 276.6mm and my Z height is 276.9mm, how exactly to I adjust fby NAP1947 - Delta Machines
This process has been a very steep learning process for as my high school math is now almost 60 years old and memory is not what it used to be. Any way we know the X axis runs between the X and Y towers and the Y axis runs on a line perpendicular to the X axis and straight back to the Z tower. As none of these are parallel to the lines between the adjustment screws setting the printer up should bby NAP1947 - Delta Machines
OK, I think I am getting a handle on this, yes I have 3 bed screws. If I use a clock face to explain, the towers are located as follows, X tower is at 8, Y is at 4 and Z is at 12. The screws are at 7, 3 and 11. If I understand this process 2 of the screws should lie along either the X or Y axis. Mine do not. For your information I am using a 1/4” flat aluminum bed which is heated. This is Epoxyby NAP1947 - Delta Machines
Dlc60, good technical article with much of it very way over my head and understanding. I read the 3 point process very carefully but this seems to be for a Prusa type printer not a Delta. I could find nothing that helps me solve my DELTA_SMOOTH_ROD dilemma.by NAP1947 - Delta Machines
Dlc60, I am trying to calibrate my FLSUN Mini using the manual method and have been having problems because the guides I have followed all refer to final adjustments to the “DELTA SMOOTH ROD” setting which I cannot find in any version of Marlin I can download. I tried to search for the “DigitalDentist” pages without success, can you provide a link to those articles please? Thanksby NAP1947 - Delta Machines
To close this thread I tried the speed sensor light and failed to get the prints I expected. I have removed the auto levelling feature and will setup using the manual calibration method. Hopefully that will work.by NAP1947 - Delta Machines
I am using manual configuration of Marlin for my FLsun mini Kossel printer. I found the auto levelling process too inaccurate for my printer mechanics. My issue is after I get the Z0 position set for centre plus each tower I still need a minor adjustment to the Z0 centre position. The process I have been following (Build A 3D Printer.eu) tells me to adjust the DELTA_SMOOTH_ROD_OFFSET I cannot finby NAP1947 - Firmware - Marlin
Hello, in the spirit of helping the developers of Smoothie, I have been trying to buy a SmoothieBoard here in Canada. No one has them available, they seem equally hard to find in the US (but import penalties from there to here are significant). I can find other boards that state they are Smoothie but appear to be clones. Are real Smoothieboards still available and is so where?by NAP1947 - Smoothie
Update, I could not make the BLTouch work and could not find help by searching the net or from the manufacturer, I sent it back. What I have tested is the lamp and reader from a rotational speed sensor left over from a robot experiment. It is a very simple plug and play on the original micro switch board connector, 3 leads instead of 2. Run M119 with nothing between the reader and light and it shby NAP1947 - Delta Machines
I have have found the main part of my issues. Before I tried G33 this morning I used M119 to check my limit switches, the effector auto calculation switch was very inconsistent, I tried to adjust and it stopped working altogether. I did some research and ordered a BL auto touch optical switch from Amazon, it should be here Wednesday. I also found q lot of lateral motion in the hot end pivot moby NAP1947 - Delta Machines
Good morning, worked late (for me) and made some more progress. I built the arm lengths using a jig and each one measures 222mm centre to centre. I need to measure from the top of the verticle riders to the centre of the arms, will post. For the base plate I reversed the knurled knobs in the base plate brackets so the knurled part is on top of the bracket, I had to lightly file the hole in the brby NAP1947 - Delta Machines
Hopefully last issue. Printer is passing all G33 tests and ending up with .1 to .15 mm errors. Effector Offset calculates out to 0.0. However, doing a test print of a ThingiVerse test pattern the nozzle touches the base plate in the Z upright area and is stringy at the X and Y upright areas. I have run the auto level (G33) tests numerous times with consistent results and the towers are all at 90by NAP1947 - Delta Machines
