Sorry, two Precision Piezo boards to a single pin on a Ramps 1.4 (or other boards I guess). In other words: Will shorting two green wires in to a single one work? Or will everything explode?by bowzee - General
How do I hook um two boards on a single pin ? Is this even possible?by bowzee - General
Dust, thank you for your reply. So a low-pass (or averaging etc.) filter solves it? Wow, that is the exact opposite of what I would expect, in fact, by experience, usually these fans will stop working below a given (usually high) DC voltage. But I will try you suggestion anyway.by bowzee - Firmware - Marlin
I am having a problem with my part cooling Sunon maglev fans, they will not rotate when the PWM is lower than 80% in default conditions and 60% when using the FAN_SOFT_PWM and SOFT_PWM_SCALE 0 directives. Is there any way to make them work with a lower value? Maybe lowering the frequency even more, as to get an occasional blip?by bowzee - Firmware - Marlin
MMcLure, thank you for the reply I had no idea, that is it then!!! Unfortunately I am using 1.1.9 because of the current "stable" status, but after your reply I will upgrade. Big Thanks!!!by bowzee - Firmware - Marlin
leadinglights, thank you for the reply The piezos are below the base plate, so they are always at room temperature. The error is in the hundreds of microns range (500, 800, etc.), not anything like you described (BTW, congratulations for that!). The sensitivity has been tweaked to the limit. I really hope that someone comes up with a solution for this, manually tweaking each point of the mesh tby bowzee - Firmware - Marlin
Hi, I could not locate a way to do this automatically, this is why I called it a request. I am adding a set of 3 piezo probes to an Ultimaker clone attached to the print table base plate knobs. Two of them are located at the left and right front corners of the plate and a third one is at the rear middle of it. I turns out that the piezos are unable to generate a correct UBL mesh because, due toby bowzee - Firmware - Marlin
@Moriquendi, OK, well, I think that we will wait until you make version 2.86 with 24 VDC compatibility available... HAHAHA!!!by bowzee - General
@Moriquendi what about changing a few resistors on the board, will this make it 24VDC compatible? (I believe that the op-amp will take up to 32 VDC)by bowzee - General
@Moriquendi thanks for the blazing fast reply. I am concerned about the voltages and if chips will be fried, so a detailed schematic would be nice. We (a group of friends) have assembled some Ultimaker-2-like machines but we are using non-standard voltages (mostly 24 VDC). These lack any automatic z-measuring, so this is why your boards might be an interesting upgrade provided that the entire macby bowzee - General
Hi, I have a few questions: - I was unable to locate the schematics for the board with the mosfets (v2.85?), is it available? - Are the three piezo sensors connected to a single resistor (R1?) on this board? bowzeeby bowzee - General
Hi TheTechnicalNoob, Optical fiber lasers have been out for quite some time now (BTW, no relationship with fiberglass whatsoever). These are quite inexpensive if made in China. bowzeeby bowzee - MetalicaRap
bobc, thank you for the reply. I use the Repetier Host, so it would be more adequate to say that subprogram treatment should be a functionality of either this program or of a (possibly written in Python) pre-processor? I guess that I will search for these solutions then! Regardsby bowzee - Firmware - mainstream and related support
I am trying to make a filled square using Marlin, and it is/was my understanding that it can be implemented using some code similar to this: G90 G0 X0 Y0 G1 X20 Y0 M98 P101 M98 P101 M98 P101 M98 P101 M98 P101 M98 P101 M98 P101 M98 P101 M98 P101 M98 P101 M30 O101 G91 G1 X0 Y1 G1 X-20 Y0 G1 X0 Y1 G1 X20 Y0 G90 M99 but this does not work. Is this an issue with Marlin? Is there any other easy wayby bowzee - Firmware - mainstream and related support
