Hello... Is there any way to smoothie tells that there are some error in config file? Thanksby eslavko - Smoothie
Found error myself... One of comments line are longer than 132 characters and that cause problem. ... actually the last line of config was too long and has that efect.... After removing that comment all things work as should.by eslavko - Smoothie
Hello... I have issue with homing. I did test only for X (alpha). I do all controll over new web interface. Smoothie binary is latest from web, board is v1.1. After I issue home X they goes to the switch and home properly with retract and rehome. The issue is that coordinate is not set as should be (-5) and I trip limit switch if I issue G0X0. I expect that after homing the axis is retracted 1by eslavko - Smoothie
Hello.... Some time ago I see video for simple Z probe. By design the gantry move to the rear right corner where pickup the steel ball with magnet, then go up for few milimeters and after that does measurements. To leave the ball it goes to the same corner and goes down to predefined height and then just slide to the side to leave ball in socket. Now I can't find it again. Does somebody knowby eslavko - General
Hmm something is wrong here.... I belive this is schematic for my board but just 4 drivers are soldered... And there are no manual trimmers. The current is set by digital potemtiometers from software. VDX your schematic seems to be for some other board.by eslavko - Smoothie
There are A5984 on the board. And Sleep pin just cut power to motor. So not that functionality by chip itself. But smoothieboard has digital potentiometers to adjust current. So that can be done by software. Just don't know if that is already done.by eslavko - Smoothie
Hello... Is it there some way to reduce current when stepper is in idle for longer time? I have CNC with DQxxx stepper driver and works all fine with cold motors. (they drop current to 1/2 after 0.5 second of silence in step pin) But now I build other machine and use smoothie to control it. And after some tests motors is hot. And current is set as should be. (I did measure current if somethingby eslavko - Smoothie
The difference is around 1.5mm. So easy job for spring, but the accuracy is not. And when I try to plot that I got something like parabola curve so not easy to compensate. And real pulley should be under 10mm to got good resolution. And that mean longer pulley and bigger difference.by eslavko - Mechanics
Hello... I read a lot about spectra line for drive instead of timing belt. As I read the major trouble is how to drive it. On one side there are just turn around drive wheel and possibility to line slip. The other side have line joined on center of driving shaft and then all needed length are wrapped around shaft. There are no slippage but tension change dependant of motor position. I got idea tby eslavko - Mechanics
Hello... Just one comment here... Backfeeding 7805 is not good idea at all!. Read the datasheet! May work but how long. In 7805 there is reverse path that can be destroyed with high current. So if you have 7805 with only (empty) 100nF capacitor on input and you apply 5V to output terminal there is "unlimited" inrush current flow backward to charge 100nF capacitor on input. So it's depends on hoby eslavko - Sanguino(lolu)
Hello... I finnaly managed to open pcb file. As electronics is my area I can say folowing from what I see in board. - used FET is PH7030L and has RdsON worst case 11mOhm (at 5V on gate) So if I assume 10A for heatbed that's mean over 10W of heat dissipation. And there are two FETs close together. So the board will overheat here. But as the heater doesn't work all the time in most situation theby eslavko - Sanguino(lolu)
Hello... I'm in building proces for my 1st printer. For electronics I just ordered Sanguinololu V1.3B. But there are some bugs/mods proposed. Sadly I can't find board layout (or gerbers) for that board. I know that backfeeding USB with 5V is bad idea, and this should be solved. But for heated bed and extruder there are just two pins on connector. I don't think that can carry 10A+ for hotbed.by eslavko - Sanguino(lolu)
