As can be seen in the image the X-Axis is not really stable. The blocks should be 10x10x10 mm, and the top and bottom are perfect. The waving does not appear in the Y-direction, it's only in the direction of the bed movement.
Each block was printed at different speed, from medium to dead-slow. I limited the acceleration and in the last block I also limited the non-printing speed so the bed would never experience a higher acceleration than with the printing itself. But the wave effect remains. And it's also remarkably repeatable so it looks more like a synchronisation error somewhere. Does anyone has a clue, or experienced a similar effect ?
This is the issue of your z-axis rather than x- or y-axis because printing speed doesn't have any influence on the results.
All above suggestions concern z-axis.
 because it's PrintBot its z-axis has the following disadvantage
differently, but essentially everything works except the Z-Axis. Problem: The one issue that I seem to be having is with any kind of movement with the Z-Axis. When it moves, whether from the LCD... aligned and the entire Z/X-Axis carriage moves very freely along the vertical rails. The bearings appear to be fine. I then wanted to narrow it down to being the firmware, and not electrical... wrong before) Moving onto the firmware. I've played around with the default settings section in Configuration.h with no avail. Regardless of how low, or high, I go with any of the max acceleration
. Basically, I think I'm looking for a software-defined method of coordinating the X & Y movement of the projector's output to the printing surface (presumable a tray of photo-sensitive SLA resin... to concentrate on. With such a large printing surface/volume (37"X x 24"Y x 28"Z), I don't know how I would implement a DLP projector to cover such a large surface and still maintain the level... that could be used for selecting colors, resin injection/flow, resin tank elevation, curing LEDs, temperature/ventilation fans, laser scanning, router speed, etc. The X & Y movement guide bars
I'm seeing the following pattern on my Prusa clone: The first layer prints OK, layer adhesion to the bed is good. The second layer shows the weird gaps. On larger pieces, or with an increased feed rate, it sometimes gets so bad that parts of the second layer detach and are dragged across the print. I get the impression that this effect is worse when printing in the "top left to bottom right" direction, but not as bad when printing in the "top right to bottom left" direction. This occurs with multiple filaments and materials. I've already tried to manipulate the flow rate, temperatures
A few weeks ago a shift between layers in the y-direction (from the front to the back of the printer) of my Makerbot Replicator 2 appeared. All prints have some small shifts between layers, but if the extruder has to move large distances (e.g. when I print the same object near the front and near the back of the print bed), they can reach up to 2 cm or so. In those cases the extruder seem... of the shifted layers are quite reproducible. From what I understand problems such as these along the x-axis, are generally caused by broken cables, which are pressed upon as the extruder moves
I'm having an issue with my new Prusa i3. (This one: https://www.amazon.co.uk/gp/product/B01DLIRDFW/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1) For some reason the Y and Z axis are swapped when I print Gcode files, even though all the axis move correctly when I manually move them with the interface on the LCD. Also, if I try to print an STL file, the Z axis moves in one direction more than it is actually limited to, and then does the same again in the opposite direction when the print starts. Anyone know the solutions?
/ mmPerSecond By summing up all the move times, we have the total estimated print time. I've seen that some forums state that the 3D print time also depends on some settings on the 3D printer, especially Acceleration X, Acceleration Y, Acceleration Z, Jerk, and Z-Jerk. I'd like to make it possible to use those values to more accurately calculate print time; however, I don't understand how those values affect the move time: How should Acceleration and Jerk be considered; and, how do they speed up or slow down the print time? How should I edit my formula in order to include Acceleration
Ironing out all my worries before buying my first 3D printer. I'm looking at getting the da Vinci miniMaker 3D printer as my first 3D printer, but it doesn't come with a heated bed. On my previous question about heating beds effect on a print, I was told that I need to use a raft to compensate for the absence of a heated bed. What I want to know is, does the software that comes with the printer allow the creation of rafts whilst/prior to printing? Or will it create rafts if need be?
in a paper printer carriage assembly with a stepper motor (NEMA17). But there was not enough space to fit the axis of the nema 17 at the exact spot of the older DC motor axis, in short, the axis are not in the same place. The question is : if the axis is not in the exact same spot, will it affect the movement of the carriage or not at all ? I supposed it would but i'm not sure since the carriage is limited in movement by the rails and that we still move the belt around.
not sure if this should be a separate question) I would have also asked whether aluminium PCB heatbeds are worth the additional cost, over standard PCB heatbeds, but for the slightly less common dimensions of 200 mm x 300 mm, the costs, of an aluminium PCB heat bed, are roughly the same as standard PCB. Some thermal imaging pictures, comparing standard PCBs with aluminium PCBs, would be appreciated. I am keen to buy an aluminium PCB heatbed for my P3Steel v.4 printer, which has a larger build area of 200 mm x 300 mm. So, after some searching, I found this MK2A: MK2A 300x200mm Aluminum Heated
