Ball screw shaft offset measurement using Dial indicator
Since the ball screw wobbles quite much, some tuning to the bearing blocks was made and after around 30minutes tuning the shaft offset was measured to around 50-60µm (micrometers). This […]
Electronic Wirings from Motor to Power supply
Since the printed motor mounts are too flexible to use with the CNC machine, some steel HM12-57 mounts with C5 bearings was ordered from AliExpress. Mean while, the electronic wirings […]
Bottom frame temporary assembly and installation
In order to be able to finish up the aluminum parts which are slightly different in thickness, the bottom frame needs to be assembled temporary as rigid as possible. The […]
Rubber gaskets to lift up the main frame
To reduce some vibrations that may cause metallic noise, rubber gaskets are used under the main frame. The rubber gasket was a 150x200x30mm plate which was sawed with desktop band […]
Assembling the Z-Axis Gantry Plate prototype
The gantry plate for the Z-axis worked out well. One problem that was encountered was that one of the HGR15 block threads was miss placed on the factory and was […]
Making of the X-axis gantry plate prototype.
Not much to say here more than -> check the video below Feedrate 600mm/min and plunge rate for rail holes was 50mm/min since there was an error in the gcode…A […]
Vertically Adjustable 1605 Nut hosing screw holes
There was a problem with the nut hosing alignment vertically with fixed screw holes so some vertically adjustable screw holes had to be routed on the existing Y gantry plates. […]
Assembling the CNC Machine using Prototype gantry plates.
Since the steel T-nuts from China is on their excursion trip somewhere who knows where, i printed t-nuts with my 3d printed. The idea is to use the openbuilds tee-nuts […]
Cleaning of HGH15 and HGH20 blocks using IsoPropanol
While the T-nuts are on the journey from China to Finland (well they turned back to China but hope they will resend them soon…) I decided to clean the HGH […]
Y-Axis Gantry Plate Prototypes
The Y-Axis gantry plate was machined with my old smaller 300x400mm work area CNC. The holes for M5 bolts are 50mm wide and has sink holes for the hats of […]
