Microstep driver Hello, i'm new to 3d printing and i'm trying to build a prusa i3 ,i had some problemes finding a a4988 stepper motor driver on local stores, so im considering using a CNC microstep driver like this one 1304024800_HP4015B.jpg mod_embed_images_loadimage('e0dd682f85528cb1a611ac89e73dd0d9', 'https://reprap.org/forum/addon.php?1,module=embed_images,url=https%3A%2F%2Fwww.damencnc.com%2Fimages%2Fproducts%2Ffullsize%2F1304024800_HP4015B.jpg', 'https://www.damencnc.com/images/products/fullsize/1304024800_HP4015B.jpg', 'https://reprap.org/forum/addon.php?1,module=embed_images,check_scaling=1,url=https%3A%2F%2Fwww.damencnc.com%2Fimages%2Fproducts%2Ffullsize%2F1304024800_HP4015B.jpg', '', 385396, 800, 400, 'Loading image ...', false); on my ramps 1.4 , so is it possible , and if so what are the complications of using a such a driver ? https://reprap.org/forum/read.php?1,385396,385396#msg-385396 Thu, 13 Aug 2026 14:43:57 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,385396,387162#msg-387162 Re: Microstep driver https://reprap.org/forum/read.php?1,385396,387162#msg-387162 Haitout General Thu, 24 Jul 2014 08:46:31 -0400 https://reprap.org/forum/read.php?1,385396,386928#msg-386928 Re: Microstep driver https://reprap.org/forum/read.php?1,385396,386928#msg-386928 reprap.org]]]> Traumflug General Wed, 23 Jul 2014 16:08:18 -0400 https://reprap.org/forum/read.php?1,385396,386452#msg-386452 Re: Microstep driver https://reprap.org/forum/read.php?1,385396,386452#msg-386452
i also have another problem with the pc power sublly , once i connect it with ramps it goes down (i have checked and there's no short circuit ).]]> Haitout General Tue, 22 Jul 2014 13:06:28 -0400 https://reprap.org/forum/read.php?1,385396,385842#msg-385842 Re: Microstep driver https://reprap.org/forum/read.php?1,385396,385842#msg-385842 Traumflug General Mon, 21 Jul 2014 05:45:26 -0400 https://reprap.org/forum/read.php?1,385396,385664#msg-385664 Re: Microstep driver https://reprap.org/forum/read.php?1,385396,385664#msg-385664 Most firmware just toggle the line high low for a step,and the 4988 etc don't care, most larger drivers require a minimum pulse width, and possibly harder to guarantee a minimum time between a dir change and the first pulse being sent.]]> Polygonhell General Sun, 20 Jul 2014 15:31:28 -0400 https://reprap.org/forum/read.php?1,385396,385604#msg-385604 Re: Microstep driver https://reprap.org/forum/read.php?1,385396,385604#msg-385604 We have had great luck with most of the drives we used, but not the Leadshine drives.

We believed the pulse width coming from Marlin/ramps was too short and the Leadshine drive treated it as noise and ignored all step/dir commands. We looked into adding a delay or lengthening of the step/dir commands in Marlin, but we moved on as we had other options.]]> joeb1 General Sun, 20 Jul 2014 12:39:22 -0400 https://reprap.org/forum/read.php?1,385396,385401#msg-385401 Re: Microstep driver https://reprap.org/forum/read.php?1,385396,385401#msg-385401 Haitout General Sun, 20 Jul 2014 02:41:51 -0400 https://reprap.org/forum/read.php?1,385396,385400#msg-385400 Re: Microstep driver https://reprap.org/forum/read.php?1,385396,385400#msg-385400 Here are some inexpensive ones with free shipping:
