View Full Version : budget matching of electronic components.

Hello there, I am about to embark on an mdf constructed router build, I have sorted out the mechanical design but I am finding it difficult to match electronics under my budget. my maching will be using 10mm leadscrew (this) (http://cgi.ebay.co.uk/TR10x2D-Trapezoidal-Spindle-Acme-Ballscrew-Leadscrew-/310185130078?pt=UK_BOI_Metalworking_Milling_Weldin g_Metalworking_Supplies_ET&hash=item483879785e#ht_1359wt_1145) and I am thinking of using these: motors (http://cgi.ebay.co.uk/3-Stepper-Motor-3-1Nm-Nema23-439oz-1yr-Warranty-cnc-/120739013161?pt=UK_BOI_Industrial_Automation_Contr ol_ET&hash=item1c1c9b2229#ht_511wt_913), driver (http://cgi.ebay.co.uk/CNC-TB6560-3-Axis-Stepper-Motor-Driver-Controller-Board-/250789782935?pt=UK_BOI_Industrial_Automation_Contr ol_ET&hash=item3a643c6597#ht_2616wt_981) and power supply (http://cgi.ebay.co.uk/24V-15A-DC-Regulated-Switching-Power-Supply-CNC-/260782357032?pt=UK_AudioElectronicsVideo_Video_Tel evisionSetTopBoxes&hash=item3cb7d6fa28#ht_2107wt_992) the theme of these parts being, big motors cheap everything else. these parts come to around 135 my budget is around 150 ish. I wish to cut mdf and perhaps some aluminium. though I am not too worried about the speed at which I can do those things. So finally my questions ! Are these parts good enough for my application? Is there something that I can get that will be better that will fit my budget? Are these motors overkill? If I go smaller I can upgrade the other components etc. generally recommend me some cheap but reliable cnc electronics and in return I will do a detailed build log :).

Not sure about the motor driver but I dont think you are going to get decent 24VDC 15Amp power supply for 20. If your power supply isnt stable its going to create lots of problems for you.
