Continuous printing with a Double Wham, start another print before you start cleaning the first! The Double Wham contains:
I have observed this in two MARS units I have repaired for others. In both the trolley was so tight in the rails that when the stepper motor attempted to raise it it could not, or "missed a step", causing the motor to "cog"² and not actually move one or more steps. When that happens the firmware thinks the Z-axis has moved but it has not; this fouls up the internal count and the firmware now has absolutely no idea of where the build-plate really is. Missing one or two steps may not be immediately audible as is the "grinding" of a complete jam. In both of the printers I repaired the Z-axis trolley was incorrectly adjusted so as to be absurdly tight within the rails, requiring 4 or 5 lbf to be moved. This is a pretty good YouTube video describing proper adjustment of the Z-axis trolley. The fellow calls it "calibration", which of course it is not as nothing is "calibrated" against any standard--it is simply an adjustment.If you do not know this and just hit "home" -the printer tries to approach the absolute zero point with its platform.
The 3DJake Flexible Buildplate System was specially designed for easy removal of the finished parts. WB Magnetic Base with 3M adhesive resistant to harsh solvents and chemicals like resin, mean green, and isopropyl alcohol Thanks to a specially patterned surface, our steel plate has improved adhesion compared to most original platforms, which greatly increases the success rate! The sequence of the first downward motion of the trolley at the start of a print job is as follows:Small Footprint but Large Printing Size】Mars 3 has a large printing volume of 89.6mm*143.43mm*175mm. Chitubox Pro Slicer】Comes with the Chitubox Pro Slicing Software for FREE one year, no need to pay for it within the period. the firmware resets it's internal "turn counter" variable; (a value of 0 = the physical zero trolley position;
It is vital to understand that in printing, in response to a G-Code "goto zero" command, the Z-axis ALWAYS first moves to the physical zero position (as determined by the limit switch) to establish the actual zero starting point--it has to to determine the trolley's actual zero reference. It and then rises to the logical "zero" position if set. Also, the "Home" function will always move the trolley to thee physical zero position regardless of how the logical "Z=0" position may have been set. If one had dealt attentively with the topic, one would have realized that one must print out a spacer with the old platform BEFORE modification, which must be inserted between the flag and threaded spindle. Additionally you need to replace the 2 screws with matching ones, because the original ones are too short, of course.
I have an option "yes, but I won't buy from AliExpress": this would entail interest inn finding a distributor in the USA. The instructions about how to level with a piece of paper are kind of garbage, and prone to all sorts of adjustments and error. However, there's an easier way to do this. Loosen the 2 set screws on the build plate to allow it to move freely. Hit the "Home" button to bring the build plate down as low as it'll go, so that the springs are compressed against the LCD screen without the resin tank in place. Square the build plate up so that it's oriented correctly with the LCD screen, and while it is still sitting on the bottom of the tank tighten the set screws on the side. Tighten the screw on the right first, and when that's in as far as it'll go then tighten the front screw. Powerful COB Light Source】XY resolution: 0.035(4098*2560px); The heat sink system works 50% higher heat dissipation efficiency than ordinary sink. As an alternative, there are recently the flex plates. These thin metal sheets are held to the platform with the help of a magnetic intermediate layer. After printing you can detach the flex plate from the printing platform, bent it and your model will detach from the flex plate easy. -easy peasy The home function of the printer does not ensure that the last set zero point is directly approached. Instead it works like this:
