The drivers I bought have a much more robust Toshiba 6600, mounted on a substantial heatsink, so I would have thought reliability would be OK. I can understand large commercial devices may have different requirements, but for my home router I can't see what more is needed. I hope to learn from this Forum on this subject, as I have with everything else to get me to this point.
Plenty of people using cheaper drives & quite happy with them, really depends what you expect from your machine, what you are doing with it & what level of support you want. The branded drives Gerry has mentioned have a lot of advantages which could be crucial if your using your machine as part of a business where reliability, speed & support are needed.
If it's a hobby machine that does odd jobs & if it breaks down there is no rush to get it up & running again then the cheaper drives may well fit the bill but don't believe everything you read about them
Lots of the cheap drives don't use Toshiba chips as claimed, they use clones which are inferior, don't have the same quality control & are much cheaper to buy. I use a few different CNC forums & have seen quite a few posts where people bought cheap drives & had problems either from the start or after a few months of relatively short use.
I use Leadshine drives because I wanted something I knew was going to last & not give me any problems, I am ok paying the extra money to give me that peace of mind as I don't want to let my customers down because the machine has broken down & spares will take weeks to arrive. On the other hand I fixed a machine for a friend not to many months ago who had done everything as cheaply as he could, maybe he was just super unlucky but the first breakout board he bought was broken when he got it & 2 of the 3 original drives didn't work, informed the seller, there were some back & forward emails & then he received another set of parts, breakout board was ok this time but again 2 out of 3 drives didn't work, more emails & photos back & forward & again another complete package turned up. This time all 3 drives were OK which was a relief
That was 3 breakout boards & 9 drives he had been sent & the seller didn't ask for any of them to be returned. Problem was all that took months as they came from China by slow boat. He then had 2 spare drives & a spare breakout board, he is now down to one spare drive as I had to replace one just recently. He has emailed the seller again but not had a reply yet.
