Several questions regarding the use of the printer

Post by onki » Fri Jan 18, 2019 5:13 pm

Hi,

I have printed some objects already and I am quite happy with the printer although there are some weak points.
Maybe there are solutions to my questions:

Since the printer is pretty loud and I am printing over night I am thinking of using the Trinamic TMS2130 drivers for X and Y-axis.
I am currently biulding a case based on the IKEA Lack table but this is not enough to get it more silent.
As they are controlled through ISP additional wires must be soldered (from SD-Card port).
In addition the GT-2560 looks pretty nice to me. Are there revisions of this board available who alredy have this connections included in the layout?

After printing some parts I have noticed that the printed parts are slighttly smaller than the original drawing. A printed disc with 125mm diameter only shows 122mm. Is there any calibration of the stepper motor possible through the frontend or do I need to change the values in the source code?

I observed that the the Z-axis stand is not very stable against the Y-axis. When I press the button to release the filament from the extruder I see the whole upper part is moving around and might have an influece on the bed alignment. Is there any cross strut available (or a different solution) to stiffen Y-axis with Z-axis?

I get the impression, that my printing speed is not at its best and a print takes forever. What are recommended speed values for this printer for 1st layer and other layers which are fast enough but not causing poor printing quality when using PLA?

Best regards
Onki
