OK.... this is what I have... Prusament and Colorfab PLA/PHA are made for prinitng at high speeds... If you have a slower machine like mine avoid all PLA that prints using a higher temp (215°). I ordered some PLA from Form Futura and have been quite happy with it. I won't be bothering you guys again.by herrgray - Printing
Hi Guys, Going a little crazy here... Can't seem to find a good distributer for plastic... I built my machine about 4-5 years ago.It is mostly aluminum and is rigid as well as heavy. The fastest it will move is 1800mm/m, Printing is 1600mm/m, Hotend is a Dyzend-X (using a v1 Smmothieboard) I have tried: Fabadashery PLA I went though alot of it, it was always consistent. Unfortunatly they areby herrgray - Printing
Hi, Last update here: The DM542Ystepper drivers from Stepperonline were pretty much plug and play... No need to change microseconds_per_step_pulse They were setup using common annode as here: Smoothieboard Docs I am quite happy with the setup now and the machine seems to be working quite well...

Hi, I don't think I am going to get any help with this as the only one who can definativly answer the question is the person who designed the board and wrote the Smoothieware... The information you can find on the net is incomplete... Suggestions of should work and may overclock are not super helpful... Things such as the step-rate is up to 200kHz and step-pulse is 2ms, is more helpful in helpby herrgray - Smoothie
Hi, Why don't you just grab +5v from one of the limit switches and do open-drain? Grayby herrgray - Smoothie
Hi, I am trying to speed up my 3d printer and wanted to add some external drivers for the x and y axis and am trying to get my head around the step-rate on the Smoothieboard. I bought a set of drivers (DM332T) that had a maximum step-rate of 60kHz and I could not get them to work... Setting microseconds_per_step_pulse to 8 would cause it to drop 25% of the steps moving 75mm instead of 100mm.by herrgray - Smoothie
Hi, I have noticed this as well... try going up to 1.2.6, they seem to have fixed it there. Grayby herrgray - Slic3r
Hi, I switched over to PLA from Faberdashery and the problem went away... I assume the stuff from Innofil3D had water in it or airbubbles. Thanks for the help. Grayby herrgray - Printing
Hi, I am slowly going insane here... I have made about 100 test prints using differnt slic3r versions and variaing tempertures from 185 to 200C and the problem remains. Plastic is Innofill3D PLA in black. Layer adhesion is excellent... Bed is set at 65C and the PLA sticks well to the bed. It will print cleanly then smewhere in the print the plastic will stop flowing then pick up again. The Extruby herrgray - Printing
Hi, I know alot of people are running Budaschnozzles but mine has been inconsistent at best. I assume my problem has to do with the fit of the thermister and resistor. The nozzle came completely assembled so I did not bother to look at it much (I also have to add so many people out there are talking about how great their works...). I am using RAMPS and Marlin configured correctly for the honeyweby herrgray - General
Hi, I tried both brass and Stainless steel M8 threaded rod on my machine for all axises. With about 20 turns per inch I really had to push the steppers to get my machine to move at decent pace. At max rpms the steppers are not producing alot of toque and will skip steps when changing direction. The rods also tend to whip around alot (yes even straight rods) and will cause wavy prints. I have sinby herrgray - General
Hi, OK, I think I have it now.... Thanks for the input everbody, I now know the machine was skipping steps. You really have to set the mm/s mm/m settings down really low for machines with screw drives. I also switched firmware. I am now using a modified version of Marlin v1. It is modified to work with the Printrboard and is alot easier to set up than the repetier firmware. One of the changes iby herrgray - General
Hi, LoboCNC: Thanks for the input, I don't quite know if it is vibration causing the motors to skip... The machine is quite stable. ShadowRam: Here are a few code snippets from the repetier v.83 firmware... /** Maximum feedrate, the system allows. Higher feedrates are reduced to these values. The axis order in all axis related arrays is X, Y, Z Overridden if EEPROM activated. */by herrgray - General
Hi, waitaki: I took the video with my iphone... I am not an expert when it comes to makeing videos with that thing... There is no binding in the axises (not much anyway... the thing jogs around with no odd noises) Ohmarinus: The board uses Allegro A4982 Stepper Drivers... I though the printrboard was supposed to be a good controller... Thanks for the compliment on the machine? bobc: What end iby herrgray - General
Hi, I am new to this sport and have built my own machine. It is using a printrboard with repetier v83 and 1.6a Nema 17 motors. Problem is, I can't tell if the motors are skipping steps while printing or if they are making normal noises... The machine is set to run no faster than 43mm/s, checking with a dial gauge showed that the steppers were moving the same distance (ie 1mm = 1mm) consistantlyby herrgray - General
(I have Printrboard plugged into a machine I built myself. When I am in Repetier Host I can manually move the axises without any problem but when I try to print an object the x and y axises will start jumping steps only when drawing circles, the bigger the circle the more steps it skips.) getting no help with this so.... The settings are also not compatible between differnt Frimwares, I triedby herrgray - Repetier
