Apologies for not getting back to you sooner.
Thank you for your recent contact through the Craft CNC site: I have sent a reply to your email too
Quick review of your questions:
I have added a few links for you to check over both for UK and US suppliers of nema motors.
It is possible to purchase these motors here:
The web locations for these motors do change from time to time however there seems to be many sites where these can be obtained.
The motors specified on the Craft CNC are a guide and the 1.8 steppers are also suitable, however the stepping of these motors needs to change when setting up the Grbl ini file on the Grbl control. Basically the .9 step motors have a finer step than the 1.8 however this can be changed in the (text) stepping ini file. Eg 0.9 stepper = 197 steps and the 1.8= 98.5 steps
o There is a choice of motor height too the 42 X42mm refers to the XY millimetre dimensions and the 34mm or 40mm refers to the Z height. The maximum height of the machine will accommodate both the 34mm the 40mm motor.
o The critical measurement for the motors is the 42x42 as these motors need to fit tightly into the motor cut out of acrylic sheet.
• Perspex is a brand of acrylic sheet. If you speak to your local supplier, they will usually laser the larger sheets to the size required for your machine.
Answers to your questions 1 and 2
• In the Vectric machining software there is a grbl postprocessor to use for the Craft CNC machine and there is a special Vectric software controller that we supply called ‘V Transfer. This is available to all Vectric software users to download and it will look for your current Vectric licence. This controller can be downloaded from the Craft CNC site from next week. This has only recently become available, so I will add the link to the Craft CNC site from next week.
• For anyone who doesn’t own any Vectric software there are many other third party free controllers that use our generic g-code postprocessor for toolpath generation.
The ‘ whats new’ updates Craft CNC
• This is where we add the changes or offer alternative options for the Craft CNC build.
• The power plug holder is for an alternative plug to the original so either of these holders can be used to suit the power plug you have.
• The stronger motor holders have been updated. The previous supports have been superseded to improve the operation of the machine.
• The updated blue prints layout enables 8.5 users to download the CRV files. (No change in panel layout)
I think this covers all the questions so far, however if you require any other info please let me know either in the forum or through Craft CNC.
